MONTCALM ROYAL LONDON HOUSE has a total of 253 rooms. It was built in 2016 with a spa, gym, two restaurants and cutting edge meeting spaces too, giving Montcalm Royal London House Hotel-City of London an exciting new future. To the south is St Paul's, the Thames and the soaring towers of the City. To the north are the galleries, bars and boutiques of trend-setting Shoreditch. At the heart of it all, we have put our stamp on the former Royal Mail head office.
