This is a nice and modern Airbnb in a great location. The WiFi was great - I do a lot of video calls for work and didn't have any issues. Kitchen is fully equipped and there is a washer which is convenient. There are a lot of places to walk to near the Airbnb. The bed was comfortable and the apartment is spacious.
Cons: It was loud at night, shower is very small, and the second bedroom has no windows (not a huge deal since you should be out exploring Lisbon anyway).
Overall, I'd recommend this place!
