Great location and the apartment is exactly as pictured. There is a very nice view from the terrace. The space is very stylish and comfortable and has everything you need. Loved the portable hot spot, it came in handy. Right outside the door is Largo do Carmo, a nice little plaza that almost always has street musicians and has a few good restaurants and a kiosk where you can get a drink (it also has a tv so we watched some of the world cup here). The Bairro Alto neighborhood is a short walk and features lots of great options for dinner and live music in the evening. You also are very close to the Rossio train station. Just a short walk, downhill, will have you on the water or at the Cais do Sodre train station (to go to Sintra or Cascais).
Pedro and Antonio were very responsive.
This is a perfect place to stay in Lisbon and I would highly recommend it! I believe they have a second apartment in this building - if you need more space.
