My husband and I had a great time staying in the loft apartment whilst we were in London.
It's in such a convenient location, with the Russell Sq tube stop only a few minutes walk, or only 10 mins walk to Kings Cross.
The apartment is spacious with a big kitchen, and the bed is very comfy. Can get a little noisy at night, if you have the windows open, but not enough to really be a problem.
Diana was a great host, very prompt with communication, and kindly checking in with us to see if everything was going well. We were shown around by Ed, who was also great.
Overall, a great place to stay!
