Breakfast is adequate, but only barely. It's frankly rather limited compared to what one might expect from a chain hotel. I remember basic cereals presented cheaply, some a la carte options (with £ signs against them - not sure if they were free for Globalists) and some school canteen type English breakfast options. This is one of the weaker breakfasts you'd find in London. I'd go somewhere like Spitalfields which is full of hipster cafes and eat out instead.
The room I received on my two visits on the other hand was quite nice. Top floor with a balcony. Really nothing to complain about. If it weren't for the location, I'd visit more often.
