First things first, the flat is very well located in the center of the Lavapiés quarter. The whole of Madrid's centre can be reached easily by foot. We arrived very late, but the check-in went absolutely smoothly nonetheless. Communication was great before and throughout our stay. On the other hand, the flat could have been a bit cleaner overall. All in all, it's a well-located and not too expensive place to stay for a weekend in Madrid.
