My girlfriend and I stayed here for 5 nights while visiting Lisbon, our first destination on a month-long trip. It's a good space for 2, well decorated with a fully equipped kitchen and great balcony/courtyard. If you're sensitive to heat, you might want to sleep with a bedroom door open and/or with fans provided. We found these were more than sufficient. Pillows could be better.
We were told by several locals that we were located near the 'night life area', although we didn't really notice as it's in a quiet street several blocks away from the main drag. It's about a 20 minute walk into the centre of town and close to various bus stops etc. Overall a convenient and quiet location that suited us well.
