We stayed at lorenzo's place for a long week end with my best friend. We were welcomed by claudia who was really nice, helpfull!
Lorenzo's place is very clean, nice and is located in Gran Via quarter. The apartment is very well maintained, very comfortable, and has all the amenities you need for a nice stay in Madrid.
This apartment is in the middle of everything! We never had to set foot on the subway or take a cab--everything is walkable.
One little problem: the appartement is quite cold at night time and we ran out of hot water very quickly even if we didn't take long showers.
But I highly recommend this place!
