We stayed in Clau's apartment for a month.
PROS: Incredible views from the floor-to-ceiling windows (magical at night). Entire building is high-end and stylish. Front door staff was awesome - friendly and helpful every single time we met them. Huge grocery store within blocks had everything we needed. Desk in the Queen bedroom was perfect for remote work, and the Wi-Fi was very strong. Foam mattresses and sturdy beds made for excellent sleep (my husband tosses around a lot and I didn't feel a thing).
CONS: No dishwasher or laundry in unit (would not be a problem if your stay is shorter than ours - I'm only including this in case others are planning a long stay too). Laundromat is 15 min walk away. Because of the poor quality of the tap water, we had to create a complicated system for hand-washing dishes with filtered water that became a bit tedious. Also, FYI the walls are thin - we could hear upstairs neighbors easily. A noise machine and ear plugs worked for us so we slept fine.
