I stayed here for 2 weeks, partly for work and partly for vacation. The location was great with easy access to the subway (this was important for me) as well as restaurants, coffee shops, and bike/running paths! Sound can be heard from the main unit above but to be expected in a basement unit; I was out a lot but if spending a long period of time in the unit, you may notice it. Sijia was very hospitable and friendly, quick to respond to questions (such as adjusting the temperature when requested as it is controlled from the main unit).
