Very nice and cosy apartment. We enjoyed large and comfortable beds, clean restroom and well equipped kitchen.
The location is pretty good, too. It's not the centre, but we still had a good access to metro (10-15 minutes of relaxed walk), and get to the heart of the city really fast. So if you're travelling 4-6 people, and don't need to stay in the very centre of Lisbon, you should consider this apartment, as well as two more apartments in the same house from the same owner.
