Ana's flat is quite perfect! Bathroom and kitchen are well equiped and clean, rooms are nice and cozy. There are also a lot af small details in her interior that we were really impressed of. And of course the thing that makes this flat is a magnificient view on the city. The only disadvantage of this appartment is that there is rather bad sound-proofing, so in the morning you have to wake up with neighbours who are going to work and vice versa when you come home late at night. But it's all because the building is very old and it's a kind of payment for real portugal spirit :)
Ana herself is very nice and easygoing person. She really cares about her guests and helps however she can. We were late for about 2 hours in night time, but she was waiting for us for all this time without any complaints and after that ordered pizza for us.
Would definitely recommend this place for staying in Lisbon!
