Chris was a helpful and attentive host. He answered our queries promptly and provided useful information on nearby restaurants and museums. We had a good meal at Ciao Bella one of his recommendations. He also made sure that a hairdryer was left out for us. Chris was flexible on check in and check out times, allowing us to check in at 11 am.
The flat is in an excellent location, close to Kings Cross/St Pancras, in walking distance of the British Museum. A few minutes walk takes you to Russell Square tube with excellent access to central London and beyond. There's a Waitrose supermarket on the doorstep and plenty of eating and drinking options nearby.
The flat is near the top of the building, up some 60 steps. Not a problem for us but might be an issue with heavy luggage as there's no lift. It has a quirky, artistic feel with large papier mache animals on the walls and lots of books.
Whilst it was clean on a superficial level, there was ingrained dirt, for example around the windows and grouting of tiles in the bathroom. We bought a pizza that needed heating and found the oven was very grimy. Depending on your viewpoint you might regard the flat as lived in or a bit tired and in need of a deep clean and freshening up.
I think it's notable that there's no photo of the bathroom. It has a shower over the bath but no curtain or screen so you have to be careful to avoid spraying water over the floor.
To conclude: great location, helpful and responsive host, reasonable price , good sized apartment but don't expect somewhere pristine.
