We arrived by air to OPO. The appartment is easy to find after a short walk from Trindade station (Aliados is closer but not worth the transfer.)
We received a warm welcome from Maria and enjoyed the Port and Nata she gave us on the balcony in the sunshine.
The apartment is comfortable, well appointed and makes a good use of the available space. The street can get noisy at night but ear plugs sorted that out.
The location was perfect for us with many resturants nearby (check out the recommendataions book in the apartment it was very useful.) It was easy walking distance to all the major attractions to be seen around Porto.
Overall a thoroughly enjoyable 5 nights and we would recommend it to anyone looking for somewhere to stay in Porto.
