I stayed at Ana's apartment with two friends in early June 2017. We had a lovely stay: the apartment was extremely clean with great decor. Ana greeted us on arrival and showed us around the apartment: everything we needed throughout our stay was there from the beginning.
Ana was extremely helpful and very quick to respond by text / email to any queries we had. She kindly recommended some local restaurants which were fantastic!
The apartment is located in Alfama which is close to Graca: both are lovely areas of Lisbon with hidden side streets and a few places from which great views of the city can be seen.
I would highly recommend a stay at this apartment :-)
