This apartment is well located, just a 20 minute walk to the touristy/central areas. We were warmly greeted by Paulina, who showed us around the unit and made sure we were settled in.
The apartment is clean, comfortable, and fairly well equipped with all you need (including a small coffee maker which is essential :-) and a washer). There is a nice solarium but unfortunately we did not get around to using it more. The only minor drawback is the elevator which seemed to get stuck on the 5th floor because the door does not close tightly. Hopefully the building maintenance will take care of it.
Ana and Paulina were very responsive on the few occasions we had questions, which was greatly appreciated. On our last night, Ana helped arrange a car to pick us up to take us to the airport early in the morning.
As mentioned previously, the central area is about a 20 minute walk which was very manageable. There's the metro and train nearby, plus plenty of restaurants, mini-supermarkets, and stores in the immediate vicinity.
It was a relaxing and nice time spent in Lisbon! Thanks Ana and Paulina!
