Lovely experience all around!
The apartment is located in the heart of Lisbon, just a short walk from countless cafes and restaurants. The place itself is very charming and comfortable- the apartment is spacious and well equipped in a fully stocked kitchenette (plus very reasonably-priced mini bar with a good selection of Portuguese wines) and bathroom. And there's even AC which is quite uncommon in Portugal from what I hear. Wifi is working very well so you can totally planning on working remotely if that's your thing.
And the hosts are lovely! Communication with Patricia and Paolo was very easy. Patricia checked me in, helped me upstairs with a heavy suitcase and showed me around the apartment. Highly recommend staying here!
