I never met Sergio but we were in constant contact chatting. He was very helpful and nice.
The place is extremely well located, in front of a bus stop and a block from a Metro station from where you can connect to everywhere. You can walk to some interesting places and you have a supermarket and restaurants really near.
The place is a little bit old and the floor (as the whole building) is tilted but it was very clean and with everything in place. It was fine for our last days of travel.
