When I got there I was met by the hosts, and they couldn't have been more polite and attentive. They patiently explained everything about the place, and gave me some nice tips about the city.
The building is located in the heart of Lisbon, just a few short steps from a subway station and bus stops. The area is also dotted with several restaurants and upscale stores. It's really well located.
The apartment itself is spacious and well decorated, with nice details like the Portuguese tiles on the walls. The kitchen is fully equipped with modern appliances. The apartment is comfortable, very well kept, and it has everything you could possibly need during your stay.
I couldn't be more satisfied with the hosts and the apartment. I would definitely stay there again.
