Our stay at GISELLE Suite Was nice and the communication and service level from Mamta, one of the co-hosts was extraordinaire and we felt taken care of immediately. Even if we had a minor issue with the power (the key card activating the power broke), she was able to help us out within minutes in the late afternoon. So I definitely want to praise the host's/co-host's friendliness and great service (quick introduction to the apartment, recommendations for the area around (restaurants, medical service, etc), availability in general). The apartment itself is according to the pictures and description from airbnb.
What I need to say is: I would now prefer a location nearer to the city centre as it is quite a walk back and forth if you want to visit the classics, e.g. Il Duomo, Piazza della Signoria but you can check this beforehand via Maps or something. So just my personal feedback. Unfortunately, the status of cleanness wasn't what I am seeking for when renting out an apartment as a lot of surfaces were dusty, cobwebs could be found on the wall and in the cabinets above the bed and as we got company in form of a cockroach, you can imagine my facial expression. So always close the windows 24/7, guys! :)
We went there at the end of May, meaning: A/C in use most of the time, closed windows, warm temperatures as soon as you switch off the A/C (which was located in the bedroom) :)
If you consider most of these things I just listed, you should be now well aware what you can gain from this cute apartment near Santa Maria Novella and the train station Santa Lucia, but also what you need to keep in mind if you decide to go for it.
