Joana's place is perfectly located close to the Universities. I was in Lisbon for a conference and the location of her apartment was perfect for me. It is also close to the metro station which will get you downtown in a few minutes. There is air conditioning in her place, which was nice during some of the hotter >30C days. The kitchen is fully equipped and there are several grocery stores nearby. The cafe right across the street is also pretty good. Joana was very easy to reach and clear regarding check in and check out procedures. I would definitely recommend staying at her place while in Lisbon.
