We had an overall great experience with this accommodation, the apartment was clean and nice, and the couch bed was also comfortable enough. Floride gave detailed information about accessing the apartment, check-in and check-out went seamlessly. The only small problem I can think of is the noise, as airplanes are regularly flying very close right above you, even at night. (This is not very uncommon in Lisbon, however, you might want to consider this if you're not a great sleeper.) We were a group of four people, two of us were totally fine with this while the rest couldn't sleep very well because of the noise. All in all, I would recommend this apartment, especially for shorter stays.
