We had an excellent stay in Porto! Mario provided us with very clear directions and was waiting for us upon arrival at the apartment. The room itself had everything we needed and corresponds 100% with the photos, descriptions and other reviews. No remarks what so ever when it comes to cleanness! The location is absolutely amazing as it is in the middle of everything that's important. There are countless bars and restaurants within 5 minutes walking too for at night. Mario was very helpful with determining what's worth visiting and what's not. Also had great suggestions when it comes to restaurants. We had an amazing stay in Porto without any complains!
