Beautiful apartment, so much room and location is excellent. Lisbon is a city that never sleeps so I would recommend earplugs if you want to sleep well as 3 of the rooms got a lot of street noise.
We were a group of 4 and the apartment had everything and more we could ask for.
Supermarkets within walking distance and an excellent Uber service exists in Lisbon if you get tired of walking everywhere (cheap)
I would strongly recommend this apartment and Joana (the host) was extremely helpful.
