A really convenient apartment; you can walk to the water or to restaurants or to the metro in minutes.
The apartment is cozy so if you like intimate spaces this could be a good option for you. I'd say it's a particularly good option for students looking to be central in Lisboa.
Kleber and Glaucia keep the place in pretty good shape and as long as you're ok with the 5 flights of stairs (I consider it a bonus :) ) you should enjoy it as much as I did.
