The Wellington is a great place to stay if you need to be close to the central action of London. Many areas are within walking distance and the Waterloo train station is directly across the street.
I stayed in a room with my wife and daughter, which met our needs perfectly. It was a decent size, was clean and had moderate updates. The building is quite old, so it is quite worn in many areas. For example, carpets, walls and railings in the main stairwell. Cracked paint and built in dirt around windows etc…
So if your preference is new and shiny, this won’t be for you. However, we all enjoyed our stay.
The breakfast each morning in the pub was perfect, lots of options and the staff and service was excellent.
I would definitely recommend the Wellington.
