We really enjoyed our 3 months stay in this cozy apartment and this place is highly recommended! The apartment is super comfortable and has everything you could need. There is a dishwasher, washing machine, well equipped kitchen, large comfy bed, AC, good and stable wifi. There are also some touchy and stylish things in the apartment as well as great books and guides which could help you to explore Lisbon.
The neighbourhood is amazing, you will be close to everything. You can find beautiful parks just 5 mins walk from the apartment, also a lot of brunch spots, local restaurants, supermarket, pastelarias, everything is super close and walking distance.
On the top of that, Ian is a super host who helped us a lot with great advises what to explore in Lisbon and nearby. He is very friendly and easy to communicate, it was a big pleasure meeting him!
