The overall stay was satisfying. The apartment was spacious and exactly the same as seen in the pictures.
We had a couple of problems though.
The wifi did not work in the main bedroom. The router was in the sofabed room, so the signal went off from the hallway.
The door of the laundry machine did not open after it finished. So we could not take out our laundry and had to wait until the next morning when the engineer came to fix it.
One more thing we'd like to address is the manager's lack of service-oriented mind. We had heavy luggages but he did not offer any help when we had to carry them way up to the 3rd floor. We understand he had a back problem, but we would've felt a lot more welcomed if he at least showed some willingness to help.
