The apartment is a surprisingly sunny basement. Clean and very tidy. As mentioned by other travellers one can hear and feel the tube passing just below from 6 am until 11pm. There was road work in the street above, so noisy background during working hours. But we were out most of the time. So not a huge incomfort.
The staff is extremely helpful and the location perfect to visit London.
We got this place as replacement following sudden cancellation of another property rented on air B&B 800m away. We are grateful that this place was still available 2 days before our planned trip.
