The apartment is exactly like the photos: is small but it have everything you need. The bed is comfy and the whole apartment is really clean. The only thing I don't like is the bathroom. It's inside the kitchen, although it has door and a good air extractor.
The neighborthood is perfect for young people, because there are a lot of pubs and restaurants.
Finally, Sofía is the perfect host. She was available for everything, and she gave us a lot of information about the city and the restaurants.
Thanks for everything Sofía! Our time in Lisbon was perfect.
