So my partner and I used this apartment whilst we were visiting the NOS festival as it's situated between the festival and Lisbon. It only took us 10 minutes in an uber each way and only cost around £7.00. The apartment is modern, clean and has everything you'll need for your stay. Be warned - there are about 4 flights of stairs to get to the apartment, but the view from the living room window is well worth the struggle. Our host was accommodating and helpful throughout our stay.
There is a lovely Italian restaurant just around the corner you need to eat at and you can reach a super-market within a 10 minute walk. I would deffo recommend this place.
