Both Alfredo and the apartment were great. He made us feel very welcome and made sure we settle in well. The apartment is very nice and cozy- I'd say it looks better than on the photos. The location is perfect for exploring central Madrid- pretty much everything you want to see is walkable from there. There's also lots of nice bars and restaurants just a few steps away, which is handy if you're feeling lazy. All in all I definitely recommend it!
