Merce's apartment was absolutely perfect. Just as described, it is close to the Metro and all major tourist attractions but located in a nice and quiet residential area, surrounded by cafes, local restaurants and shopping. The apartment was really spacious, spotless and quiet. On the day of our arrival, we were allowed to check in early and we were impressed by the elevator actually opening into the apartment. There is PLENTY of room. I HIGHLY recommend it.
We would definitely stay there again in a heartbeat!
