I had a great time in Lisbon!
First I was concerned the way from the Meteo station to the apartment could be exhausting, since it's mostly walking uphill. But you get used to it and in the end I didn't mind it at all.
The apartment was nice and clean and Agostinha was a great host. When I arrived she showed me around and had information and tips for the city provided.
I didn't see her often, since I was out in the city most of the time, but I had a wonderful stay in Lisbon and I would definitely again choose Agostinha's place!
