We stayed at the blue&white appartement for 2 nights (2 persons). The room is small but was well put and clean, with air conditioning which is a plus if you suffer from heat during summer. We were welcomed by André who gave us a number a tips about where to eat and what to see in Porto, which is nice. The check-in time is a bit late in my opinio (after 14:00), but André told us where to left our luggage close by (the Trinidade metro station has a great locker system), and we finally managed to check-in a bit earlier.
