I stayed at Param's for ten days and I had a great stay. Param is a very nice host. He is welcoming and really cares about your comfort, you definitely feel at home. He was very helpful, advising me on the nearby restaurants, where to have brunch, etc.
I would heartily recommend Param's house for anyone looking for a cosy and peaceful stay in a nice part of London, wether you are here for business or holidays.
