For spa hotels in Florence, we would start with how you want to use the facilities. Palazzo Castri 1874 and Ville sull’Arno offer different reasons to investigate a stay: the entry arrangement, a separately booked exclusive session, or a named room’s bathing feature. Choose the experience that matters before comparing the accommodation.
Start with the two actual Florence addresses
Palazzo Castri 1874 gives its address as Piazza dell’Indipendenza 7. Ville sull’Arno lists Lungarno Cristoforo Colombo 1/3/5. Use these actual addresses when comparing the accommodation with the outings you want to make.
Use where to stay in Florence when the wider base choice is still open. Luxury Hotels in Florence, Italy compares a different accommodation shortlist. Here, we would let the spa arrangement lead the hotel comparison, while keeping the rest of your intended stay in view.

Castri: an appointment and a hydromassage preference
Castri describes a 153-square-metre spa operating by appointment, with set times for families with children. Its 30-square-metre warm hydromassage pool extends outdoors into La Limonaia garden. The same description names a Finnish sauna and Turkish bath.
We would consider this for someone who wants a soaking-and-steam session between other plans. A hydromassage description answers a different preference from wanting to swim lengths. Make the activity you actually want decisive, rather than treat every water facility as interchangeable.
For a family, ask which session can accommodate the actual party before building the day around it. The stated family times make that a specific enquiry; they should not become a promise about every child’s admission or an unrestricted session.
Exclusive use: a separate booking with a seasonal limit
Castri’s exclusive-use offer describes the entire wellness area for a 90-minute booking, with a minimum of two people. The service is unavailable from June 1 through September 30. Bathrobes, towels and flip-flops are listed as included in that access.
We would compare this when spending the session together without other guests is the point of the booking. Treat it as a particular offer to arrange, rather than a feature automatically attached to any room. For a summer trip, its stated exclusion matters before you select the hotel for this purpose.
Ville: an included hour still needs an advance slot
Ville sull’Arno’s FAQ states that every room type includes one hour per day of spa access in the room rate, subject to advance booking of a time slot at the front office. This is a defined daily entitlement with a reservation condition.
We would give that arrangement weight if a short daily session is what you want. Choose a slot around the other parts of the day you have already committed to, rather than assume you can arrive whenever you feel like it. Inclusion and a confirmed time answer different questions.
A guest who wants several visits in the same day should ask about that intention separately. The stated hour is a useful comparison point; it should not be expanded into unlimited entry, a treatment allowance or a guarantee that a particular slot remains available.
A treatment cabin is different from a guest room
The Il Segreto della Villa spa description names a warm pool, biosauna, sensory showers and steam room. It also describes the Terra e Acqua treatment cabin’s cherry-wood hot tub and a Raxul cabin. The spa page limits simultaneous use to eight people.
We would separate an interest in those shared spa facilities from wanting a bathing feature in your own accommodation. A treatment setting can be the reason to make an enquiry, but it does not describe the bathroom of the room you will reserve. If a particular treatment interests you, arrange that service specifically.
For a stay with children, confirm the current admission arrangement directly for the ages travelling. Being accommodated at the hotel and being admitted to a particular wellness session are separate requirements. Let the confirmed arrangement decide whether the planned session belongs in the family’s day.
Villino Spa: compare the actual bathing alternatives
In Villino Spa, the Deluxe rooms are described at 22–26 square metres, with river views and a Turkish bath or hot tub. The Junior Suites name a riverside terrace and an open-plan hot tub.
We would begin with the feature you intend to use. Someone specifically wanting steam should establish which offer supplies that alternative; someone wanting a tub should do the same. The category’s alternatives should not be combined into a promise that every offer contains both.
The open-plan wording is also worth considering before making the room choice. Decide whether that arrangement suits the people sharing. It should not be silently transformed into a separate enclosed treatment room or another bedroom, and the category name does not establish a bed roster or permitted party.

Outdoor swimming has its own calendar
Ville’s outdoor pool is described as open from May to September, weather permitting. That seasonal outdoor facility should be distinguished from its wellness-area pool and the named room features.
For a trip centred on swimming outside, let that calendar carry real weight. For a stay focused on a reserved wellness session, compare the entry terms instead. An autumn booking should not depend on assuming that the outdoor facility remains open beyond the stated season.
Choose the access arrangement you will use
Give the intended experience a clear place in the stay. Compare how entry is arranged, whether a separate offer is needed, and which feature belongs to the selected room. That makes the spa a concrete accommodation choice instead of a label.
