Silvia was very kind, answered our many questions with great patience and helped us with a lot of information on site.
The appartment is really nice, and equipped with all you need.
Place M. Pombal (with the sightseeing busses - "Grey Line" Company was good) is in walking distance through Parc Eduardo VII.
The only restriction for the app. is caused by the noisy airplanes above the Campolide neighbourhood. However, there is a bedroom in the centre of the app. that has no windows - here it is OK to sleep even if you are a bit noise-sensitive.
Thanks for a really pleasant stay!
