We found it very easy to walk to central Lisbon from this lovely little apartment. Tram 28 runs virtually by the door and the Metro is about 15mins walk. It is easy to use the Metro for the Airport and the station.
The apartment is entered through a narrow door and up a steep flight of stairs but once inside the flat is light and airy with air con and the compact space is cleverly fitted out with a fully equipped kitchen with washing machine and dishwasher. There is even a balcony with table, bench & chairs with a view over the west of the city.
We would definitely use this place again if we returned to Lisbon and as there is still so much to see and do there it is highly likely that we will be back.
