The apartment is in a great location - just far away from the hustle and bustle (very quiet location) but everything easily accessible. The place could benefit from a lick of paint here and there (main bedroom mainly) but was comfortable for a family of 4. There was a funny smell but something which goes with an old building in Madrid :-)
The fact there isn’t a lift didn’t bother us at all. Our 3 year old loved counting the stairs up...around 40 I think ;-)
