We really enjoyed our stay at ORMs apartment very much. It's very close to the city center of Oporto, so you can walk to all attractions, bars and restaurants. The only downside of the central location is, that also during the night you'll hear the cars drive past. The apartment itself is very nice, clean and equipped with everything you need. Also the contact with the guy from ORM (unfortunately we forgot his name) was very kind, he gave us tips where to find what and answered our questions.
