The apartment is in a perfect position to visit Lisbon: all points of interest in the city center can be reached on foot very easily. The public transport is also very easy to reach.
The apartment is small but has everything you can need. It is also neat and very clean.
The host, André, was very kind and always ready to help us. He gave us a lift to the airport and provided us with helpful information on what to do and see in Lisbon.
In summary, I would strongly recommend staying in this apartment when visiting Lisbon.
