It's a charming apartment in the very heart of Lisbon: all the sites are at your doorstep! The place is also quite spacious (has a separate bedroom and a living room/kitchen). Everything is exactly as on the photos. It was good to find a heater in the bedroom as it gets chilly in Lisbon at night if you come in the fall or winter.
The area has a couple of restaurants nearby, which can be a bit noisy in the evening, but there are blinds on the windows and I also used earplugs and slept very well. The only thing I noticed is that the coffee machine which was in the kitchen did not work. At first, I was excited that it's there (it's a capsule-based machine, pretty fancy!), but it did not make coffee... I hope Miguel will fix it and you will enjoy a cup of good coffee in the morning.
This place is worth the money, and I would recommend it for a stay in Lisbon. Great place for a single person or a couple.
