I can only highly recommend this apartment.
The couch and bed are extremely comfortable, there is an AC which makes it pretty cool when the weather outside is too hot and the design of the apartment is also very nice.
The location is amazing (right in the center of Lisbon) close to many cafés, restaurants and bars. Also a supermarket is 2min away which came very in handy.
There was also a very nice welcome basket and the host Patricia was extremely helpful and communicative for any eventualities.
