This is really a great apartment for a family citytrip to Lisbon (we are a family of four with 2 teen-kids). The apartment itself is spacious, clean, and the pictures on the website are accurate.
Above that, it is absolutely the location that makes it perfect. So central to everything in downtown Lisbon (Baixa, Chiado), and in a quiet traffic-free street at the same time. A supermarket is next door, and there are plenty places to drink/eat/shop in the downtown neighbourhoods.
We had a quick hand-shake meeting with Erina while checking-out. During our days in Lisbon Erina was very responsive via WhatsApp.
