The place is awesome! I recommend it 100% if you want to be right in the center of Lisboa for an awesome price and hosts, cat included :)
We liked the place a lot (and got to do some exercise as well) and we had the opportunity to try the Kong restaurant at the bottom part of the building, make sure to check it out as well!
It's a very centric place, the location is perfect if you want to see Lisbon by foot.
