We spent 3 days and 4 nights in Florence at the end of our trip around Tuscany. Sumiyo was very friendly and helpful, kept us updated about weather forecast and surrounded attractions (Bardini Gardens, restaurants, etc.), took care of our arrival and departure (booked a taxi). Apartment was very clean and comfortable with some food and drink supplies from Sumiyo. We did not mind stairs (apartment located on a last floor of the old building) and eventually were very tired at the end of the day to pay a lot attention to noise from the street (cobblestone pavement and narrow street create echo effect from traffic and pedestrian voices below). Definitely recommend this place - very brief and enjoyable walk to all Florence attractions!
