I stayed at Naresh's place with my mother for a return trip to London. The location is great (short walk to soho, which is great for restaurants), and I felt perfectly safe there. Considering that it's just off of Oxford Street, it was moderately quiet (or at least as quiet as central London can be). Naresh was a great host as well. It was very convenient to drop our bags off at his shop before our room was ready. The apartment itself is a nice set-up, and it's well-stocked with food and toiletries. I would certainly stay here again.
