We had a wonderful time in Porto and Sven's apartment was definitely part of our great experience. Location is excellent, close to everything yet quiet at night, with all amenities we needed for our week long stay. Sven provided information about apartment and Porto in advance so we were familiar with the place before we got there. Check in was flawless and Sandra gave us few tips as well. We had a great time and would like to visit Porto again and stay in Sven's apartment.
