Jorge is a wonderful host. Very friendly, gives all the information of the apartment and the neighbourhood, you need.
The apartment is a lovely two bedroom with all the amenities one can think of. We were the two of us and was very comfortable in the flat. It is on the top floor, a little climb from the entrance of the building but if you're walking all day long up and down the hills of Lisbon, a few more steps at home doesn't matter.
The flat is located in the centre, in Bairro Alto with loads of little restaurants and bars around. It can be fairly loud on weekend nights but Jorge kindly provide earplugs that will lock the noise out.
I highly recommend Jorge's apartment and would definitely stay here again if I'm back to Lisbon.
