Large spacious flat. Plenty of space and bedrooms for a large family or group. There is a really cool old elevator that was really helpful and fun to ride. Close to all the sites you want to see in Madrid. Very safe area. Plenty of shopping within half a block of the place. My only issues with the space were the large beds had very firm mattresses that may not be comfortable for all. The showers were very narrow and cramped. My kids even commented how cramped the showers were so if you are larger person keep this in mind. My final thought is the space has a clothes washer which worked great but there was no dryer. We had to hang dry our clothes and they too several days to dry. The host Mar was great! She was funny, friendly, helpful and very responsive. Overall we had a great stay in Madrid.
