The studio was clean, private and the location was perfect. It's only 30-40 mins from central London and it has easy access to transportation, like bus stops right outside your door. Gareth provided exactly what he described and there was hot water, a radiator, towels even some products for dishwashing. Gareth was very helpful and gave clear instructions.
The only drawback is that the studio is on the 3rd floor and the stairs are very narrow and dangerous. It's hard to step on and to carry laggages.
But overall, I definitely recommend this place.
