A great place to stay with everything one can need away from home - from every appliance needed, through cleaning and washing supplies, to some food and wine to welcome us on our arrival.
Ana's place is super clean and the temperature inside is comfortable even on hot summer days. The bedroom upstairs can get a bit hot when you leave windows closed for the day, but it is easily remedied with AC.
Ana is a great host and shared a lot of interesting and useful info on the neighbourhood and Lisbon in general.
As a bonus, you get the nicest neighbours we have ever meet in our travels - even treated us to local food (snails!) and beer :-).
The location is also excellent: in a quiet district, but close enough to buses and metro, so it's very easy to travel to other parts of Lisbon and city center (we recommend zapping!).
The only minor issue can be (for some, not us) the proximity of the airport: the planes fly very low overhead and are pretty loud. However, we got used to them pretty quickly and we slept like babies through them zooming overhead.
Overall, we cannot recommend it enough! We are looking forward to revisit when we are in Lisbon again.
