Positives:
Very central location
Very nice staff
Spacious and high quality furniture
Clean and well equipped kitchen
Large, clean bathroom with great shower
Negatives:
No air condition means the temperature becomes too high for me getting a perfect sleep. There are floor standing fans, and you can open the windows, but the noise from the trams running by the street right outside makes you want to keep them shut. Keep this in mind if temperature and air quality is important to you.
All in all, a great stay. Would recommend.
