João met us when we arrived and was very friendly and helpful. He showed me to the parking (a couple of streets away) and showed us around the apartment and the shared garden. He also gave us lots of tips and information about the city and the neighbourhood.
We were surprised by how much more spacious the apartment is than it looks in the pictures. Excellent use is made of the space and there's way more storage space than we needed.
The area has plenty of restaurants and cafés and there's a Lidl supermarket round the corner. It's a short walk to the centre and there are bus and metro stops nearby too.
We'd definitely stay at Ana & João's apartment again next time we're in Porto.
