The location was great. I loved that it was outside the tourist area, but still close to Atocha and Retiro. There’s a grocery store nearby as well as playgrounds. You’ll need to bring your own shower soaps and things. The blanket for the pull-out couch was minimal and hard for my kids to share. We were there briefly and didn’t ask for additional items, but you may want to be prepared with time to shop and make sure you have all you need.
We had trouble with checking in but it may have been an unusual circumstance.
