I am trying to decide where in Portugal I want to live, and I booked Ricardo's place as a way to try out the Parque das Nacoes neighborhood. I'm afraid that may have been a mistake, because all I learned from this experience is that I want to live in Ricardo's apartment full time!
It's a great space, with great views. I was here in January when it's cold, and thankfully the heaters worked great (amazingly not all apartments in Lisbon have heat, so if you're considering another place be sure to check that it's heated in the winter).
This place isn't in the center of Lisbon where most of the tourist attractions are, but it's really not that far away either. And the neighborhood is both quiet, and also full of all of the necessary conveniences. The shopping center across the street has everything I needed, so if I lived here I'd probably not travel outside of a few block radius for weeks or months at a time.
