This is an excellent unit.
First, let me tell you the things about this apartment that are great: the location is remarkably central. Just 2 stops on the tram from Santa Novella station, and a very short walk from Belfiore station to the building.
The building is very safe and your area is accessed with a passcode.
It is a simple elevator ride up to your area, but the stairs are nothing daunting, in case you should opt for that. The unit itself is extremely clean and everything is brand new. The room has a safe, it is a good size, the bathroom is very clean and brand new with excellent water pressure. The bed is very comfortable, and the linens are brand new including providing extra duvet in the closet if you would like to use it.
The room also has a great AC unit, which I did not use. There is also great natural light both in the bedroom and its bathroom. Also, the host graciously provided soap/shampoo in the bathroom (not something always provided). I also noticed the commons area was cleaned by a cleaning service everyday. The unit did not have any street noise despite being on a central street.
I was in room 7 so there was a few stairs from the "main" commons area into that unit (as if you were going to an attic). The room itself does have a sloped ceiling so anyone tall may find it uncomfortable. I am 5 feet tall, so I was fine with everything. There is also an excellent wifi connection I was able to use before getting a cellular plan.
The only thing I will say is that there is some noise from other guests because of the "commons" area, which has the kitchen. As such, depending on how late or early your fellow "housemates" get going in the morning or come back from a night out, you may hear them hanging out in the commons area and talking (there are quiet hours from 22:00 to 8 am, but it didn't seem strictly adhered to, which I understand). Also, I am not sure who I could hear, but there was one unit where I heard everything the couple did - from the Netflix movie they watched, to the massive fight they had the first night, to the LOUD makeup sex they had the second night. The good news is I had terrible jet lag and wasn't able to sleep so they didn't impact my sleep.
Last point, the host was incredible. I decided last minute to extend my stay in Florence. Unfortunately, this amazing unit was all booked but the host was so helpful and allowed me to keep my luggage in the commons area until my next stay allowed me to check-in.
Communication was fantastic with an extensive introduction about the unit, how to access it and how to travel to it. There was also some great pointers about where to dine. Any follow up correspondence was always consistent and quick, regardless of the time of day/night.
Overall, my congratulations and thanks to this amazing host. I'm sorry I was not able to extend my stay here, but look forward to coming back the next time I'm in Florence. It is certainly great value and quality.
Thank you!
