We had a great time staying in Luisa's home. The room is clean, nicely decorated and well located, just perfect for a few days visiting Lisbon. There is only a minor issue: the portuguese post accross the street who, occasionally, loads and unloads stuff in a noisy way.
Regarding the hosts, Giani, Luisa's husband, is really helpful and kind, passionate about history and foreign languages. We had a great time speaking with him. We didn't have the opportunity to meet Luisa, but we would have liked to.
