Rosa's apartment was at a great location, within walking distance to many of the local sighs. It worked well for 3 people for 2 nights, but would probably be more difficult if we had stayed longer.
Rosa is highly energetic! She explained everything quite clearly and gave suggestions of where to go. We were welcomed with a lovely bottle of Spanish. She also reserved a taxi for us as we had to leave by 6:30. I look forward to returning to Barcelona some day.
