Ruty was there when we arrived and offered to help us up with our bags up the four flights of stairs (80+). The apartment itself was superbly located, only a 3 minute walk from the main square and most of the main attractions of Madrid.
Ruty spent a few mins giving us all of the details of the apartment and also showing us a local map and giving us some pointers on things to do in the area which was very useful. The apartment came with everything you needed, towels, soap, shampoo, cooking products and even detergent for the washing machine.
The apartment is not large, but it was fine for 2 people and would of been ok for 2 adults and a child.
The only slight issue was you could hear everything that was going on outside and there was some minor repair work taking place during our stay (all done now) which was very loud after 9am - but not the hosts fault whatsoever.
