I stay in Lisboa last week with my girlfriend and we were very confortable in Miguel appartament. From the house we went on foot until Rossio, Cais do Sodré, Praca do Comercio... In spite of the hills, the walk was always agreeable. Moreover the appartament is close to one of the characteristic miradouros of the city and close to the elevador da bica. Not far there is also the tram stop, were you can take the famous tram 28. To stay in practice the appartament is on the last floor (4th or 5th i don't remeber) of the little building and there isn't elevator. Only zone questionable side the bathroom, it si very small... But if you will stay in lisboa for a few days like us, you will not have problems. Thank you Miguel!
