My friend and I stayed in Cosimo house for 2 nights. First of all, it is a unique experience - house is really old with terrace on the roof with amazing view. House is small with high stairs, so it is good for a solo traveller or a couple. There is everything what you need - shower, kitchen, fridge, plates… we really missed wifi, however information in Cosimo house description is correct, we just missed this fact.
As we travelled in February and weather was not very good, we experienced that flat is cold and with high humidity. Heating is possible just with air conditioner and we used it, however it started to make loud sounds (Cosimo promised to fix it for other guests).
Cosimo is really nice guy - he is answering to messages quickly, met us on time, help to park a car and even gave us a bottle of red wine as welcome present.
