Very chick, spacious and an in the middle of the nightlife!
The apartment (on the second floor) is newly renovated in a very stylish way. The originally old house is located on one of the sightseeing streets (with the cable car) in the middle of Chiado. We liked being in walking distance to all the cool bars, restaurant, shops, the river and the train station to go to the beaches of Esoril and Cascais.
The apartment is very clean and fully equipped (with even a Nespresso machine!). The (new) bed is a little bit hard but was ok for us.
At night it could be a bit loud but that will be the case in most of the parts in the middle of the city.
