I stayed in the "Perseo" room for a week and found the following:

PROS:
1. Giovanna is a great host, very friendly and professional. Her English is minimal but we were able to communicate with simple words and Google Translate.

2. The room is large, clean and just like in the photos with beautiful antique furniture. It has a very nice, large private bathroom and shower.

3. The location is great as you are within walking distance to most major attractions such as the Uffizi (5 minutes), Ponte Vecchio (10 minutes), etc.

4. The breakfasts were simple but filling with toast, cereal, breads, yogurt, juice and coffee.

CONS
1. The room has no air conditioning so if you are traveling in the summertime, it's something to consider. I had to sleep with the windows open every night during my stay.

2. The room overlooks a large parking lot area for taxis and vans that operate there most of the day so I found it to be noisier than expected, especially since I had to keep the windows open because of the heat. If the windows had been closed, it would not have been nearly as noisy and if you are accustomed to city traffic/noises (I am not), it may not be an issue for you.

Overall, I would recommend the room for its location, size, cost, cleanliness and professional services of Giovanna.
