The apartment is exactly like in the pictures and like in descriptions: very new furniture in a very modern flat and area.
There are 2 things I didn't really enjoy: 1. the noise you hear from the plane from around 6.00 a.m till at midnight and 2. the lack of clean towels.
There is a bus stop that takes you to Praca de Commecio (No 758) just on the left of the building and there is Sete Rios metro station that could take you anywhere (including Sintra). She was helpful at the check in when I could reach her on the phone but totally absent at the checkout when I really needed to talk to her. I didn't meet her in person. It's an agency that takes care of the business.
Thank you and all the best!
