On the first day, Vera, give us a lot of tips about Lisbon, where to go, about the transport system, and, also, a nice map. She was kind and patience.
The apartment is very well located, (near Liberdade Avenue) you can take a metro or just walk for 15 minutes to get the center ville ( Baixa, I think). It´s a charming building, with a nice bed ( what is really appreciated after walk all day long in a city like Lisbon).
