Premier Inn Portishead

Booked an accessible room which was great but as these were added onto original building it is quite a distance from reception/parking and i need someone with me to push a wheelchair- which i dont use if its a short distance….so this limits me travelling on my own! the beds are quite low (for wheelchair user) but i have bad knees do difficult to get up! the meal deal at brewers fayre was good value and staff at breakfast were great. aToilet was a bit awkward as i only have use of one arm so added handrails can often be on the wrong side (for me). info on which way round would be useful
