This is a great place for visiting London !!
Enough space to stay with a family of 6 (3 rooms with double beds and a attic for the baby coat). It is functional, so everything is there (towel, sheets, some cooking basics like salt, pepper, oil, sponge from previous people).
The location is ideal : outside of the "congestion charge area", so perfect if you come by car (cheap parking nearby - around 20 GBP for 4 days). subway is next door and very well connected (northern line direct to Trafalgar square).
It was clean, some lamps were not working and neighbours were a bit noisy between 7 and 9pm (but like at home...).
I do recommend this place.
