The flat is warm and generally clean and the host is polite and responsive to communication.
However it is not an en-suite room as the bathroom is in the corridor, accessed from outside the bedroom. Also, be very prepared for the noise from the railway which is very loud and disturbing.
Its ok, but overpriced and disappointing. I had just finished a 12 hour day and only wanted a private area and a good sleep but feel I received neither.
I would question how this is permitted to be listed as "en-suite" by Airbnb as it clearly isnt.
