We had a nice 2-days stay at Carla & Miguel appartment.
It was like we expected from the website, clean, and we even had a home made Lisbon guide, and a present waiting for us (red, to drink ... good !)
The neighbourhood is really close to all the places you wanna go when you're a tourist (Baixa, Bairro Alto & Chiado, Alfama, Graca...) ; we only used the public transportation for the airport, Belem and the Oceanorium...
The neighbourhood id old, with narrow streets, and always people talking on a bench, or even cooking fish in the streets ! We felt secured, and happy to see this everyday-life.
