Xavier was extremely responsive to all messages, and accommodated us arriving early, which was much appreciated. The apartment is large and has lots of windows to get air. The apartment is in a great location, easy access from Metro, sites, the water. The building itself is quite quiet, although there is a municipal recycling collection location nearby that can be quite loud in the middle of the night if they are collecting, so if you are a light sleeper you may want to consider that (though then you may not want to be near La Rambla anyway). Thanks to Xavier for a great trip!
