It is a great apartment, a little compact, but had everything you'd need while you were there. The internet was down so they provided a wireless internet system, it was a bit temperamental, but they provided another option and were apologetic.
It's in a great part of town so walkable to good restaurants/nightlife, and they recommended a few lovely venues so we had great food.
Slight downside is that it's on the 4th floor, which feels steep after hours walking the hills of Lisbon.
But all in all it was an excellent apartment that I would recommend and stay in again.
