We stayed at this place in Porto for 5 nights. It was even better than we hoped. It was very bright with I think 6 or 7 large windows/glass doors with a small balcony in the corner apartment. The ceilings were high, about 3-4 metres. It was an open-concept kind of space. The place was very clean, and quiet because it is located on a narrow dead-end street that gets no traffic.
The host greeted us when we arrived (late due to a train issue), went over things and had a book prepared with things to do, and other info we might need.
The location was superb, we could easily walk wherever we wanted to go. It has nearby restaurants, grocery stores (we did some home cooking), and tourist sights- it is very close to the famous train station.
We have no reservations in recommending this apartment and host.
