The stay at paolo's apartment was very nice! It was perfect that he arranged three beds for us by request, and that we could store our luggage in the apartment after the checkout hour.
We weren't in the apartment for a large period of the day. We only used it for sleeping and sitting in the balcony, which is a really good added value to the apartment.
The location of the apartment is very central - right near the sol metro station.
If we come back to Madrid we will absolutely rent paolo's apartment again.
