We stayed at Andrea's Home for 4 nights.
Andrea is a good host. He was always helpful even when we didn't turn on the coffee machine. Coffee and cookies are comp :)
As described, the house is very close to the metro and bus station. It is very easy to go to touristic areas and bus station by this metro.
The house was not extremely clean but it didn't bother too much.
The one and biggest problem in the house is the bathroom! It takes at least 10 minutes for the hot water to flow. Moreover, the water was flowing very little so taking a shower becomes very difficult :(
