We found Joao to be wonderfully responsive and very helpful. The apartment is in a great location and with the doors closed and fan on it masked any outside noises. The riverfront, train station and many restaurants are a close walk from the apartment. The beds and pillows were very comfortable and the decor was pleasant. There does seem to be a mold and mildew problem in the back part of the apartment and a leak in one of the showers that needs to be addressed. The bathrooms are quite small which was not a problem for us but should be mentioned. We really enjoyed our stay in Porto and the apartment was a perfect base for exploring the city.
