Francisco is very friendly and we really appreciated the flat which was clean and well furnished. During our stay we also enjoyed the view on Cristo Rei and the Tejo from our room. The flat is well situated close to close to the underground "Baixo Chiado" station . It is perfect to visit the city center and to catch buses and trains. Francisco was available at any time and gave some good tips. The only négative points that some visitors may be confronted with are the steep staircase, the low ceilings and the narrow bed.
Personally I was not concerned and I highly recommend saying at Francisco ' s.
