Joana and her team were extremely efficient and helpful and communication was great. The apartment is in a brilliant location and is a very stylish place to stay in Lisbon. The stairs aren't all that bad and we had a toddler and a pushchair! There's a small supermarket on the road too which was handy and we did have a car, which was easy to park on the street outside the apartment and wasn't too expensive.
Make sure you check out BouBou's restaurant too, it had only just opened when we visited Lisbon and it was amazing!
