Worse unprofessional treatment. Stayed for 2 night...

Worse unprofessional treatment. Stayed for 2 nights charged me 368 euros then blocked 400 euros on the same card ?!! For 10 days now no refund and when I called the response was it shouldn't have happened but we can't do anything... this is illegal, and so cheap to happen from a so called Gresham.. would give nill stars of I could... never mind the redecoration work on going all over the place as well as a 23 Euro Irish breakfast... COMPLETE JOKE....STAY AWAY
