I went with two friends to Lisbon and we really enjoyed our time at Ricardos AirBnB. The apartment is not far away from a train/metro station and you can reach a nice park, a cute cafe and lots of little supermarkets. Additionally, you can visit important sights by walking.
The apartment was clean and it was everything there we needed.
Lastly, Ricardo cares about his guests and always answers quickly and enjoys giving tips and support.
