As a tourist from America, I can say this is a really nice property in an older building. That's good and bad. If you love old buildings, this one has a beautiful interior albeit with a few cracked tiles (on what I presume is the original floor). But as an old building it does have the expected creaks and groans from the doors and windows. We had some gusty winds one night and the doors and windows shook! Not Jordi's fault, but if you're light sleeper it could be an issue.
The check in instructions could've been clearer (and the wifi access is a bit unique), though Jordi was communicative in resolving issues.
The location is good, but it is a bit of a walk from La Rambla and the Gothic Quarter. It is doable, but without giving away a specific spot, the tourist hot spots are a solid +/-10 blocks. There are nearby subway stations though, and Barcelona's metro is fairly easy to navigate if you've dealt with Boston, NYC, or DC's systems.
