There is AC in ONE room only and opening windows for fresh air is not an option. So, I would say it’s good for 2 people stay otherwise, you will need to do what we did and sleep in the living room.
Location is great. You can get to public transportation (busses and ferry) within 5 minutes walk. There are many restaurants around. The location is overall safe.
The apartment is nicely decorated and equipped with most of what you need.
