This is a fabulous place to stay in Lisbon - close to the centre, just a five minute walk down the hill - but quite quiet and tucked away. The terrace is superb, the apartment is as described; clean & modern and we found it perfect for a family with 2 teenagers. The two bedrooms are quiet separate, both with en-suite bathrooms, plus there is an extra bathroom.
Cafe Nando's downstairs has essentials and there are various little supermarkets nearby. But despite the apartment being well equipped for self catering, you should really be heading out for a meal as the food (& wine) in Lisbon is truly amazing.
We were collected from the airport and taken to the apartment - I would recommend this as the office to collect the keys looks like it would be difficult to park nearby.
All in all a superb place stay and enjoy Lisbon!
