"We had a king superior room with a balcony. This was exceptional for London. But, we soon discovered AC did not work correctly. AC would not go below 25 C. Could not reset the thermostat....even on manual setting. This was a big problem!! (even in early September 2026). That said, Hotel was very responsive to addressing problem. We were evetually moved, and upgraded, to a better unit with excellent AC....so all was forgiven. But, no sleep first night...had to open balcony door and curtains. So, had to contend with street noise all night....no sleep. Our thanks to Phoebe on front desk."
