The location is good, walkable distance to the major sights in Madrid's downtown. Check-in is a self check-in, with a code given to you to access the key in a key safe at the door. There is a little lift, we didn't need to lug our luggage up the stairs. Eduardo or Raul were prompt in responding to messages. The apartment is nice and clean with 3 bedrooms, each of which has twin beds, so it's suitable for up to 6 people. There are two bathrooms, one of which is located in one bedroom. The internet is very slow, that was the only issue we had, but all else was good.
