We really enjoyed our stay in Porto. The apartment is an easy metro ride from the airport and close to everything. Pedro was very responsive and the check-in process was smooth and he gave nice suggestions of where to go. Plus, there are guidebooks in the apartment of where to go, which was very helpful. One note: the apartment has windows right at street level and the walls are a bit thin; if you are particularly sensitive to urban noise, it may be hard to sleep.
