100% recommend this apartment. The location is great - very close to the Castle, Bairro Alto and Rua Augusta. Very convenient to the metro as Rossio station is only up the street.
The apartment was very clean and had everything we needed. It was very comfortable and quiet at night.
Carlos was a fantastic host and was very responsive to messages. He also gave us advice on good restaurants near the apartment.
There is a cafe across the road called Nicolau's - they do a fantastic brunch!
Would love to stay here again and will recommend to anyone travelling to Lisbon.
