Celia's place is a great spot to come into Madrid and stay.
It's located in an area that's away for the sometimes crazy night life and 5am serenades from the street - it's nice and quiet at night. It's easy to jump on the metro to get anywhere and you're a short stroll to a great river walk.
Communication was great, and the place has a complete kitchen and the washing machine is a bonus. No elevator, but only one floor up so easy to get to. Thanks for the stay Celia!
