Ana's place is unbeatable for location.
If not for the 12 flight of stairs, this place is 5 stars and perfect. I managed those stairs in my stay there, the trick is to go slow and rest ir stretch every 2 flights. The only thing though is that sewer like smell coming from either the sink or near the fridge area when water is being used in the sink or when using the toilet. However in saying that, I will still recommend to book this place and I will be happy staying there again if i go back to Lisbon. Ana is very thoughtful and welcoming even though i did not meet her. The amenities she provides to guest is quality.
