My girlfriend and I stayed in this apartment for several days and found the location absolutely ideal. The apartment was fully equipped, including a much appreciated washer & dryer to clean our clothes. The bed was comfortable and the apartment was extremely spacious. It was centrally located and allowed us to walk anywhere we needed to go. Lots of great restaurants nearby and even a grocery store less than a block away (which seemed to be a luxury in Lisbon).
We would not hesitate to stay in this apartment again, the only two issues we faced were 1) lighting in the bathroom was a bit glitchy (it's fluorescent bulbs and took a few seconds to come on, flickering a few times in the process, not a huge issue, but a bit of an annoyance and 2) the wifi wasn't the best, and only really worked in the living room (right next to the router), but still better to have.
The apartment had great windows and we had them opened almost whenever we were there, and when closed it blocked out nearly all of the noise of the other tourists, trolleys, and cars, they were quite impressive. The bedroom was in the back so allowed a peaceful retreat from the hustle and bustle that Lisbon offered.
This is a great apartment in an amazing location, don't hesitate to book!
