We spent a great time at Casa Branca. Tânia is a very nice host : she was very helpful, available and flexible. She gave us good tips about where to eat and where to go. When we arrived, a bottle of very good wine was waiting for us, as well as water, milk, tea, coffee... She also booked our taxi back to the airport and even waited for it with us!
As for the flat, it is the perfect location to visit Lisbon. It is very quiet and yet close to everything. It is within 5 minutes' walk of Martim Moniz, Rossio, Praça da Figueira, the castle and the Alfama... The flat is really cosy and very clean. The bedroom is at the back of the apartment, so it is not noisy at all. The beds are really comfortable. The Wifi connection is also excellent. We would highly recommend Casa Branca to anyone travelling to Lisbon.
