Friendly people (hosts and doorman), great location, lightning-quick responses. Lots of hot water for my shower. I felt very safe.
You will need a long extension cord (there are no outlets near the desk) and the Internet connection is slow. But the people are very nice, and the apartment has everything else that you might need. This is my second visit. I needed merely a place to stay overnight, I did not need to work, so the limitations mentioned above were not issues.
