We stayed the night in Ashford in order to catch an early train to Brussels the next morning, so in preparing our trip I looked for lodgings near the station. Cornerstone is right in the central pedestrian area about 500m from the station, tucked away down a small accessway. We used the backdoor on arrival as that is where the SatNav led us to. Turned out we had to get a taxi in the morning because of the rain. 8 pounds taxi fare, including any booking / call out fee.
The room was small, hardly deserving to be called double, which always seems to be the case with this price range in UK. But it was probably the smallest we encountered on our trip.
Generally I thought it too costly for the accommodation level offered.
It was clean and tidy. The double bed was hard against our en suite wall and there was some small furniture. Not much room to move about.
No windows, only a roof skylight. I don't know what ventilation it had, but it did not get stuffy.
Landlady very pleasant and helpful. She prepared a breakfast tray for us as we left before the normal breakfast time, and booked the taxi.
Some strange plumbing in the en suite, but everything worked properly, and no odour problems.
Ventajas: It was clean and tidy.
Inconvenientes: Ventilation, possibly fan ducted to outside. Could be hot in summer.
Ubicación: Reasonably large pedestrian area, usual types of shops. Some reasonable eating places nearby.
