First the good: plenty of space inside and out, great location (quiet and an easy walk to the train), adequate kitchen facilities (everything including the stove and the kitchen sink was hidden behind giant cabinet doors!) for real cooking, competent and helpful staff during the day (no staff at night).
The bad: the walls are very thin, so you can hear your neighbors' conversations; the WiFi is sometimes ok, sometimes very slow; and the bathroom smelled sulfurish at best, apparently due to a sewage problem. We kept the bathroom door closed the whole time we were there and avoided going in unnecessarily.
