We stayed here for 3 nights.
The pros:
1) extremely great location in terms of train and city centre, food etc. we covered all of florence we needed to see by foot. It was amazing.
2) very friendly host
3) small kitchen with basic amenities to cook simple meals
4) clean house
Cons:
1) for 2 people, the space is bit small in my opinion.
2) quite loud at night from neighbours due to the location - if you are light sleeper, might be a problem.
Overall, a pleasant stay. Thanks Andrea.
