Very good communication, everything as described. The staff from Cris bar was really nice and helpful.
The apartment itself lies within the old city. Very clean, good money-for-value. You can reach almost everything without using the public transport. It can be a bit loud on the street during the night but a big plus is that one of the best wine shops of Porto is located in the same building.
Sao Bento station (for getting to the beach) is reachable within 10 minutes by foot.
Would recommend.
