The Mentone Hotel has a beautiful aesthetic. I stayed a single room and it had everything I needed! One gripe, the TV was not working, I came to London to study at RADA and spend my evenings dining and exploring, so this wasn't an issue, however I like to have the TV on in the background whilst working on my laptop or getting ready.
Aside from that small issue, the location is excellent, walking distance to major areas of London. A short five minute walk takes you to London Underground, the area is beautiful being a grade two listed building, unfortunately no air conditioning as stated by Mentone Hotel due to the heritage of the building, but this wasn't an issue for me in room three.
I'd happily stay here again, I didn't try the breakfast as I had food to go as I was studying early morning.
4.5 out 5, I would highly recommend and I plan to stay here next year during my next course at RADA.
