Nice little room in an apartment that looks very homey. It's not very big but if you just need a place to sleep while you discover the city, it's absolutely fine. There's a living room and a kitchen as well.
The neighbourhood is nice and despite the proximity to the airport it's also very quiet. There's not much to do in this area but you can walk to the riverfront in about 25 minutes and if you want to check out Lisbon there's a subway station about 5 minutes away. The airport is in walking distance which can be useful if you have an early flight to catch.
Communication with the host was very good and the self check is pretty easy.
