The apartment is perfect for 1-3 people who plan on exploring the sights of Madrid and only need a place to recharge between exploring. It has everything you need- cookware, some basic staples, like coffee! It is on the small side (bathroom especially), but was in a great spot near two train stops and lots of restaurants. The street is a little dark at night- but still felt safe. As with many apartments you can sometimes hear neighbors in the hall- but shutting the living room door helped block that out.
I would stay here again and I recommend this location and the hosts as they provided a lot if good info and suggestions for things to do/places to go!
