The apartment is huge, very clean and has everything you could possibly need, including lots of maps and guides about Lisbon and Sintra. The neighborhood is also very nice and has two supermarkets very close by. The pictures depict the apartment really well.
Olga is a great person and host. She waited for us when we arrived, presented us the apartment and gave us some tips about Lisbon. She made us feel welcome and even gave us a big hug before leaving.
We definitely recommend this place!
