We had a fabulous time celebrating my husband's 50th birthday. The apartment was perfect for two couples with the two bathrooms and was equipped with everything you need. The location was great with several restaurants within a 5 minute walk & the nearest Metro station around a 15 minute walk away. We bought day passes for 6 euros each day which gives you unlimited travel on the metro, buses & trams.
Public transport is excellent in Lisbon but we still did a lot of walking & be prepared for how many hills there are in the city.
We all had a fantastic time and would thoroughly recommend.
