Check-in was very uncomplicated and the communication beforehand was perfect, I got all the information needed.
The apartment itself is spacious, modern and very clean. The house the apartment is in is also a very goo one. It is right in the touristy center of Bairro Alto, in between a public terrace with a beautiful view over the Baixa and the famous Bica Funicular. Many (touristy) restaurants, stores and sights are very near.
It is a little noisy at night thanks to the international drinking crowd but since most places close down around 1am its not too bad.
The hosts were very friendly and sympathetic.
