I stayed 5 nights as a solo, senior female traveller and it suited my needs perfectly. The bed was very comfy, room quiet, bedding and towels high end. The mews house is absolutely charming and has been recently renovated. It is immaculate, stylish and well located, easy walk from Victoria station etc. The shower was terrific, lots of hot water; there's also a brand new soaking tub.
Julia is a friendly and gracious host, her young sons are delightful but unobtrusive.
Highly recommended!
