We stayed at Terme Suite for almost a month, and we had an amazing stay! The apartment is as advertised, maybe even better. The open kitchen / livingroom is great, there is plenty of space to make food and the kitchen is stocked with most of the appliances and equipment you could want. Bedroom is very spaceous, and the addition of an en-suite bathroom is great, especially if you have guests using the living room sofa bed. We stayed during the winter, but the apartment was still nice and warm which is not a given in old Florentine buildings.
Bed and bedding was comfortable (at least to our preferences), and there was plenty of extra linen, towels and pillows.
In addition to an elevator (again not a given in Florence), the interior stairs are really nice (which is normally not a thing to remark on, but I often took the stairs just to walk past the decirations and sculptures placed between the floors).
If I had to point to any room for improvement it would be that the internet connection in the building is not great, but that is a pretty normal limitation in a big part of the city and when we contacted the local staff they were very helpful in looking into alternatives. The building manager, Giacomo, is very friendly and super helpful, and was always available to help us whenever we needed anything.
The location is maybe the best part, as you basically exit the building straight out onto Piazza Santa Trinita, super close to popular sights like Ponte Vecchio, and walking distance to all the major historic center attractions.
I definitely recommend staying at Halldis’ Terme Suite, we had a great time and would not hesitate renting with them again in the future.
