We spent a great week in this apartment in Madrid. It's perfectly located in a busy street with lots of very good tapas bars. However it's not noisy since it has it's door and windows to a yard.
The apartment has enough room for two people to chill out, cook, eat and/or work.
We walked almost everywhere from Cava Baja, but if you're not into that you can always take the Metro which is just around the corner.
Also Lina and Joaquin were very friendly and easy to communicate with, and they also had a couple of great recommendations.
Good times! We hope to be back soon.
