I had a great stay at Lena's apartment! I was in Lisbon for a conference, and the apartment was conveniently located between the congress centre and downtown Lisbon. Check-in was very easy, there was someone already waiting for me when I arrived. The apartment was very clean and nicely refurbished. Just as a heads up, I would say that there is no heating system in the apartment and in the winter it can get a little cold, but they provide blankets and a small electric heater.
