This apartment was perfect for the group of 4 of us staying. The rooms were very clean and well prepared. Amenities were great and there isn't anything missing. There is plenty of heating, the apartment is warm, and the shower works great. The kitchen is a good size as are the two bedrooms and the sofa bed (which was very sturdy and comfy, and I'm 115kg/18.1st).
The location is handy as it is very close to Kings Cross Station, being only 5m brisk walk. The neighbourhood at night has a lot of traffic and with the apartment being part of a block you can hear people coming and going, but during the day it is fine.
Overall it serves us purpose and was absolutely fine for our needs. There's a coffee shop just 5 minutes away on the road towards King's Cross which was great and recommend!
