Helena's place was wonderful. Communication for check in was excellent and she & her husband met up personally for check in. We were a bit late for checking in but she didn't seem to mind. They were very thorough in their info on Porto and the apartment was spotless, comfortable and quite large. The underground parking in the building was a nice bonus. We took the bus in to the center as it would have a been a bit of a walk, which we normally don't mind walking, but we were on a time crunch to see everything. The bus was convenient to take. I would high recommend Helena's apartment.
