CitizenM Tower of London – Real Reviews & Rooftop Bar Guide

A boutique hotel perched directly above Tower Hill Station, citizenM Tower of London puts two of London’s most photographed landmarks within a five-minute walk. Opened at 40 Trinity Square, the property combines the brand’s trademark compact-room design with a seventh-floor rooftop bar that draws as much attention as the views it frames.

Guest reviews consistently highlight the location as the hotel’s strongest asset. Travelers arriving at London City Airport can reach the hotel in roughly twenty minutes by Docklands Light Railway and Tube, making it a practical base for both sightseeing and business. The building itself is a modern glass-and-steel structure that stands in deliberate contrast to the medieval stone of the Tower of London across the street.

The hotel operates under the Marriott Bonvoy loyalty program, which allows members to earn and redeem points during stays. This affiliation places citizenM within a broader ecosystem of bookable properties while retaining its distinct boutique identity.
