Our stay at Rita's place was a nice experience. She was very helpful with the check in and she even gave us recommendations. The apartment had everything needed for both long and short stays. You'll have a private room with private bathroom and a shared kitchen. The flat is located very close to the Florence main attractions and lots of restaurants.
Be aware that the apartment is located at the 4th floor with no elevator. For us this wasn't a problem, but it may be an inconvenience for elderly people for example. The heating system is an AC blower with cold and hot air. For warmer days it does the job, but I don't know about winter. Our trip average outside temperature was 10 degrees Celsius and it did a decent job, the room wasn't cold.
Overall, it was a nice experience. Great location with great host, easy to find and in walkable distances to everything you will want to do in Florence all this at a very good price. Will choose this apartment again if we'll be going to Florence.
