We stayed at Marco and Cristiana's in August and it was awesome!
First the rooms were very clean! It had a desk, fan, TV, full mirror (so useful!), closet, nightstands, towels, just about everything you need! The room had a high ceiling and was more than spacious. The washroom is right next to your room and it is super clean and modern! There was no air conditioning but we didn't feel that it was necessary to have one even though we were there when it was very hot.

The location was perfect for us. It was close to the train station and close enough to the busy areas of florence. It was also in a quieter area which is nice for when you want to have a quiet evening.

Cristiana and Marco are awesome and super friendly! Cristiana gave us a list of local restaurants to try and those restaurants ended up having the best foods we've had in Italy. Also, she prepares an awesome awesome breakfast that you'll want to wake up bright and early to eat everything and go off on your day.

All in all, everything was awesome!
