Location, location, location. It's definitely the place to stay in Lisbon. A walk away from everything while at the same time it's quiet at night so you can rest.
The apartment itself is nothing fancy, but it has everything you need and it's clean and in good condition. The wifi is fast and stable and you'll love the AC unit.
Check-in and out was quick and easy, the people of course super nice. All in all very much recommended.
