The flat was a decent sized and was well-equipped. The cleanliness could be improved - floors were slightly sticky when I moved in. The location was decent, with many restaurants and grocery stores nearby and it's also close to multiple subway stations. However, it is located on a road that is often congested, so expect to be waken up by traffic early in the mornings.
Furnished Quarters were responsive before I made the booking, and were kind enough to offer me alternative accommodation when the flat I booked had a leak. However, they became unresponsive once I moved in.
