This apartment is in an excellent location to a few steps from Piazza San Lorenzo were the Central Market is. From there, you can walk almost to any point of interest in the center of Florence.
We did not have the opportunity to meet Lucille our host; instead an administrator received us. He told us the rules of the place and provided a map with some recommendations.
The place is comfortable, but needs to improve its cleanliness, especially in the kitchen where utensils, dinnerware and silverware were poorly cleaned. Besides that, there was not dishtowel in the kitchen and the bathroom did not have a mat to step on after bathing to avoid slipping on the wet floor, which also was poorly cleaned. From the first night we had problems with the hot water. Although the next day the administrator and the owner tried to fix it, the problem continued partially.
For the location, the air conditioning, the washing machine and the small patio that provides natural light to the apartment, this place may be a good option, but definitely the host needs to improve on the cleanliness.
