I had a great experience! The apartment is exactly as the pictures show. Everything is in great condition and perfectly clean. The air conditioning works great, which is a big plus in Madrid in the summer. The bed is comfortable, the bathroom is large and the shower is great.
I loved the location. It's right by all the fun in Malasaña, yet the street it's on is quiet.
Momo was very helpful and responsive. I highly recommend it.
