The snug is a nice place to stay if you want a cheap place with good connections to central London.
Sandy is a great host. She is attentive and provides basics and some really nice optional extras.
The snug itself is very small, I would say slightly smaller than the descriptions and pictures described. Whilst set over two levels there isn't a lot of space and the bathroom isn't really sealed off, A cabin hook lock and some glass panels, meaning that even when upstairs you can pretty much hear everything so not much privacy.
This is a great space if you place to use it as a bolt hole and spending most of your time in London and looking for somewhere that allows you nice surroundings and a comfy bed then the snug is perfect. But I wouldn't recommend it if you're planning to spend lots of time in the property.
