We enjoyed our stay at the apartment, especially because the location is so good and it is an easy walk to all the important places in Lisbon. The metro station, taxi stand and locker rooms close by make the travel very easy. The apartment has everything you need and the check-in with the consierge went smoothly. It is quite loud at night because of the location (hospital and bar close by, a lot of traffic) but for us it worked well to close the windows and use the fans. If you have a very light sleep you might consider this.
Our only complained was about the shower that was not cleaned properly and needs to be fixed.
All in all I do recommmend this apartment for a stay in lisbon.
