The check-in was very fast and friendly. The apartment ist easy to find and ist very near a tube station.
The apartment was clean, but there were cockroaches in the bathroom, bedroom and kitchen which made us feel very uncomfortable.
Also, there was no stuff du wash our clothes and no stuff to cook (salt, pepper etc.) which is the basic in a apartment.
The apartment is much smaller than it looks on the pictures.
All in all, Madrid is wonderful city!!
