I found two big dfisappointents in our stay. 1) the internet connection is incredibly slow--3rd world level slow--and, 2) It would have helped had we been able to get our host to print a passport application form, or at the least if they would have been responsive to the request for help in navigating this need. Looking back on our communications, every message could have been scripted in advance, and sent out on a timer. Thoughtful as they were, there was no feeling that a live individual was on the other end when the trip got interesting.
Internet communications were rock-bottom bandwidth. The antenna is not positioned to serve the entire apartment, most importantly the Master bedroom. And sitting next to the router while trying to accomplish trip planning was also a bit of a struggle.
This location is not in the heart of the tourist attractions. We knew that, and wanted it that way. For the tourist though that would like to drop-in to the action in more popular areas, there is a little extra work involved. Several days I walked "across Barcelona" to get back to the flat. The distances were manageable to us. Barcelona excels at taking that option. But we had to prepare extra time for each event to compensate for being just off the beaten path. To us it was worth it.
