9.4/10 Exceptional! (132 reviews)

Homey feel. Nice desk staff. Comfy. Great common area for eating, water, coffee, sink and some basic dishes. In suite purified hot/cold water is great. Little gritty entry, but what can you do. Rooms are high up, higher levels in this office complex, shielded from noise.
