We had an amazing stay at Ana's and Fatima's place, both due to the nice apartment and its hosts. We were warmly welcomed by both of them with custard cakes and some Port and Ana and Fatima gave lots of advice about where to go for lunch/dinner and what places to see both in and around Portugal and how to get there. They asked several times if everything was OK and we could ask them anything during our stay.
The apartment is quite spacious compared to other apartments we stayed at in Lisboa and is only a few minutes walk from a lot of interesting points like the city centre, Alfama, cais do sodre/rossio train station. Kitchen is ok for preparing some breakfast including coffee and has a washing machine in case you're staying longer.
The street the apartment on is not very busy and the bedroom is at the back of the house so you'll have a comfy night.
Ana & Fatima just started using Airbnb to rent their apartment but just go to their place: you'll love it!
