The guest house of Mario and Domenico is fantastic. Rooms are nice and very clean, there is an kitchen and the toilets are also clean. Moreover Domenico was very nice receiving us and giving instructions to visit the city and Mario also helped us with the accommodation.
The house is close to the centre and there are amazing places to have breakfast or lunch a few meters away.
If i go back to Florence i'll go back to Mario and Domenico's place.
