Room was small, but charming and offered a place to work and reasonably fast wi-fi connection. The staff was super-friendly when checking in and very helpful. No fitness center on location, but honestly, most of the times when a hotel offer Fitness on location it is usually crap to tick a box. Indigo London Tower Hill have partnered up with a nearby (proper) fitness center for a complete workout if needed. 5 minutes on foot from the hotel, so no major inconvenience.
Breakfast was charming and the service offered had a personal touch and a friendly smile. All in all a great stay and I will most likely return.
