My partner and me stayed a Orchidea's place for 10 days and had a very relaxed time. The flat is very spacious, comfortable and has everything you need for a short or longer stay! Orchidea is a very caring and lovely host, and she was always available when we needed something.
The flat is only 15min walk from the train station & city center and there's public transportation almost in front of the house. However it's in a pretty busy street, so keep that in mind if you're looking for a very quiet place.
A very nice place to stay in Florence with an amazing host!
