We are a couple in our sixties. We stayed here for a week in September and would recommend it.
Location - about 20 mins walk from Duomo. Nice Area - quiet with some good bars and restaurants. Felt very safe walking back late at night.
Security - flat has secure front entrance and then very secure locks etc on door to the apartment. We had no worries about feeling safe and secure.
Accommodation - is up 2 flights of stairs, well-lit, no lift. Everything you need is available and works. Air conditioning works well. Bathroom and shower is excellent. Bed is comfortable. Apartment was lovely - everything was new, worked well and we felt very comfortable in it.
Transport - We walked everywhere in Florence. Took trains to Pisa, Lucca and Siena. Tram to airport.
Would definitely recommend this apartment.
