We had a great time in Lissbon! The apartment is really nice and everything was as expected from the description.
We had to take an arranged shuttle from the airport where the driver had our key to the apartment, otherwise a check-in after 10pm wouldn't have been possible.
We really liked the big living room which was perfect for having breakfast and relaxing after a busy day. The bedrooms are rather small and one has no window. However, there were some fans and with open windows and doors we had no trouble getting a good night sleep even on hot days.
The location is nice, with a lot of small shops nearby and also some street art. We definitely recommend this place.
