Ana's apartment is located just a bit north of Lisbon city center and many of Lisbon's most popular attractions. This small distance allows the visitor to enjoy a nice walk towards (and away from) attractions or pop into the Anjos metro station for quick trips; the metro station is about 3mins walk from Ana's apt. The neighboring area is also fairly residential so it doesn't get too loud at night when trying to get rest.
Ana's apt is made up of 4 bedrooms, each available to be rented separately. I don't know about the other rooms, but my room was beautiful, it had an old-fashioned decor about it - it was a great place to start and end my days. The bathroom, kitchen, and patio are shared space between the renters. During my time at Ana's place I had no issues sharing this space with others and, in fact, found the experience led to fruitful discussions. Finally, if she's around, do engage Ana in some conversation, it was a joy talking with her.
