Cila was a great host, and very patient to wait for us at the flat even with our delay in immigration. Excellent location, close to Castelo Sao Jorge / the Alfama, restaurants, and public transportation. The apartment was very clean and perfect for our stay in Lisbon.
To reach the flat take the metro to the Martim Moniz metro stop. Find the pharmacy south east of the square and take the escalator / stairs to the top. Go left at the top of the stairs onto Rua Marques de Ponta, and then take a left onto Rua Joao de Outeiro. The door to the building sticks, so push and it will open. The flat is up the stairs, second door on the left.
