We stayed at Eurostars Das Artes as a family and really enjoyed our experience. The hotel, from lobby to the room, is clean, has elevators every step of the way, and we were welcomed by pasteis de nata and infused water when we checked in. Perhaps the most welcoming, however, was the concierge who checked us in, Catarina. She was very approachable and friendly, and gave us great recommendations for sights to see and places to eat - check-in was such a smooth process with her. This branch of Eurostars is a bit further from the centre of Old Town but still easily walkable and in a nice area. Note that the minipreco grocery store nearby might be closed, as we never saw it open, even during normal opening hours! There is still a minipreco express about 6 min walk away though. Overall, this was our favourite hotel to stay at in Portugal and we would stay again and recommend!
