We spent 2 days at Maria's apartment. It was such a great experience. We highly recommend this place if you are looking for a somewhere to stay when travel to porto. Firstly, the apartment is close to a Metro, you just need to walk 5 minutes to the Metro and the train will take you 2 or 3 stops to the city centre. There is a great famous local bakery shop near the Metro. Secondly, the apartment is super tidy because everyday there is a cleaning lady and has everything you need to feel like you're at home. Thirdly, Maria is a great host, even she wasn't there the whole time we were staying but the communication is smooth and quick via messages. If she host any airbnb in other cities, we would definitely choose her.
