You can't beat the location for convenience, although it is quite noisy on the street below. However the windows are well insulated...
When we arrived, we went to see if we could drop off our bags and met who I assume is a cleaning woman. She helpfully showed us where to leave our gear. We never saw another person who worked there, ever.
We didn't know there was air conditioning, we didn't know how to use the black out blinds, we didn't even have anyone to whom we could turn in our key at the end of our visit.
A great place to stay, but they need to have an employee on site.
