This room is perfect for solo travelers in London. In terms of location, this place isn't too far from Central London, and transport is very accessible, i.e. by tube and by bus. However, the services are not 100% reliable so you should always have a plan B if you don't want to Uber, i.e. use the tube if the bus is full
Besides, with the provision of tea, coffee and towels, this place is a great alternative to staying in a hotel. In terms of safety, the neighborhood is quite safe, however when it comes to London, one should never take safety for granted and always stay vigilant. The loo and shower are shared, and always kept clean. And you should not take a shower after 10PM, which was totally fine by me. They also provide a TV that has access to more channels than an average hotel.
I absolutely recommend this place and wouldn't mind coming back if the opportunity arises.
