We had a great 4 night stay in Ruis apartment. The apartment is located perfectly for strolls and walks to all the major sights in Porto, and several nice cafes, restaurants and shops are more or less just outside the door. Just across the road there is a bar/restaurant with great cocktails and italian food, well worth a visit.
When the weather is nice as it was during our stay, some of the nearest bars and restaurants are popular among the local crowd, so it can get quite lively in the evening.
Bring your best walking shoes when visiting Porto!
