The house is very well located, close to a metro station. There are shops and restaurants nearby too. The house is extremely clean. It's well furnished, it has everything that we needed. It's nicely decorated. There are toilets downstairs and upstairs, which is very handy. The balcony next to the bedroom is great to have breakfast.
We didn't get the chance to meet Rita and César, but I can say that they are really nice and responsive from the communication I had with them. We appreciated that they offered us some pastéis de nata and some orange juice. I definitely recommend to Rita and César's accomodation in Porto, as we really enjoyed our stay there.
