Tim is an amazing host--he was there when I checked in, walked me through the flat and pointed out where plates, knives, tea kettle etc. I asked for more coffee pods and he brought them over in 10 minutes or so. He also had a list of restaurants, places to go, etc. Incredibly fast at communication and super helpful with trains. Flat is quite spacious (the water boiler room has plenty of space to store luggage), and the place was really clean and everything looked really new (I checked in early and saw Tim do a once-over after the cleaning person left to make sure everything was clean)--couch and bed were comfortable. The location of the flat is fantastic--easy to get around multiple different areas of Porto. I would stay there again if I was ever in Porto!
