We had a great stay here. Lots of contact and flexibility for check in (really helpful as our flight was delayed). The apartment was clean and had everything we needed for our stay with two young children.
Location is good - it is up a steep hill (though manageable even carrying small kids). it’s close to the metro, restaurants, cafes and shops, so really easy to get around and see Lisbon, get groceries or an evening meal.
Though there are shops and restaurants, the area around the apartment is quiet in the evenings, good for getting kids to sleep!
