We really liked this apartment in Porto. It is not close to the waterfront, but still close to bus stops and the Metro so you can easily get around. Also there are many nearby restaurants & shops on the next street. Right across the street in a shopping center is a grocery store which was very convenient. We cooked breakfast every morning.
The apartment was super clean and well organized. We could easily cook all the meals in the kitchen. There is a small foldout table to eat and we also ate on the small balcony. There was very good Wi-Fi and a TV but I don't think we used the TV. The bedroom and bathroom were both very nice. A good modern shower in the bath.
There is A/C which was a bit slow to work, but was OK after some time. We slept well each night. Even though the street below had some traffic, the room was well insulated and quiet.
The metro is about a 10 minute walk and there are bus stops nearby. The next street over is a pedestrian only street for 2-3 blocks and filled with shops, restaurants and a shopping mall.
I would definitely stay here again. Very clean modern apartment.
