Abel's apartment is the perfect location to explore Porto. It's pretty well located in close proximity to all the major sights and also walkable to the river. There are numerous bars and restaurants around (ok, the flip side is that it's a bit noisy at weekend evenings). The apartment is very modern, very clean and spacious - as shown in the photos.
We did not meet Abel himself, however, he helped to organize a very flexible hand-over of the keys upon arrival and departure with his local contact.
All in all, Abel helped us to have a fantastic weekend in Porto.
