My friends and I had a great 9-day stay in Felipe and João's appartment. The place has the charm of an old house. It is properly renovated and has everything we needed. It is located in a dead-end sidestreet of a stairway, which is nice, quiet and located in the beautiful Bairro Alto neighborhood. It is also close to Cais de Sodré station, from where you can take the metro to anywhere in town and trains along the coastline. The appartment provides a stunning view of the Tagus river.
Felipe and João are helpful and always respond quickly. They even provided us with a great guide with tips and a map of the area around the appartment. This came in very handy as it was our first time visiting Lisbon.
