Really nice apartment with a ton of space. The keypad system to access the apartment is also extremely convenient. We only stayed for a night but wish we could have stayed for more!
One note for future guests is that it's in a very hilly area (as most of Lisbon is) so it's best to have a cab drop you off there with your bags. We made the mistake of rolling our bags all the way up and I've never been so exhausted! And if you have trouble walking in general it might make more sense to stay near the water or the santa justa lift where it's flatter.
