We stayed in Susana's apartment for 10 days during our stay in Lisbon. Location-wise, it is great with quality coffee shops, cafes, and restaurants all within a 10 minute walk, and not too far from major sites, either. It is also very close to public transport and a park, so the location in Principe Real cannot be beat. Although it is a few minutes from the bustle of Bairro Alto, the apartment is very quiet and peaceful, with no noise issues at all. It is cozy and clean with rustic decor, comfortable, and has enough room for 4 people, so 1 couple has more than enough space to spread out. Most of all, Susana is very friendly, accommodating, and responsive; she is a wonderful host.
