We were very pleased with our stay. We were in room number 3 which had a cute balcony and which we found very clean. Location is great because it's steps away from metro. Hosts were friendly, although we had to wait about 25 minutes to check-in although time had been set with them prior to arrival.
Everything went well except last night when we realized walls were pretty thin (we could hear snoring from room next to ours) and when an unpleasant smell from someone's cooking spread throughout the floor (maybe bad ventilation or no kitchen door would explain?).
Although the floor does get busy at times since there are many rooms, I would definitely recommend it to anyone wanting to stay in Lisbon. Thank you!
