Location is great, right in the middle of the night life of Lisbon, close to public transportation and a lot of good restaurants.
The apartment itself was clean and organized.
Rui and Elsa are very responsive and helping!
The apartment was small for my opinion, but I guess it is common in this part of the city, this been said - I guess you don't need more than that.
*If you don't have plans renting a car - be prepared for the steep roads which can be very tiring (even for a quick jump to the grocery store)
