We really enjoyed our stay in Porto, Paulo's flat is lovely and the reception we got from Maria was fantastic, she was already waiting for us when we arrived and she gave us great advice about places to visit and restaurants etc. The only problem we had with the apartment was the noise. It is located in a very central street which is great during the day but at night we realised that is it directly opposite a very busy night club. The music was extremely loud until 5am and then there was a lot of noise in the street from the people leaving the club at 6am. We didn't get much sleep on thurs/fri and Saturday night. We would consider staying in the same building again but in a different apartment that didn't face the busy party street.
