Manuel is a fantastic host, very communicative and helpful. His recommendations for Porto were amazing - I went to the breakfast place for eclairs EVERY DAY.
The view is just as great as the photos, and the apartment is neat and clean.
As many others have noted, the location is amazing and also quite close to a lot of night life. So it gets very noisy on the streets outside throughout the night. After one sleepless night we got earplugs and that really helped :)
