I spent almost three months at Louis’, and it was for me a really good experience. The bed was so comfy, the flat is really well designed, with an awesome bathroom.
The area is well served next to 24hrs buses which go to Victoria, Vauxhall or South Kensington. According to the traffic, it can take less than 30 minutes to go to Oxford Circus.
Concerning the host, Louis is really respectful, calm and easy going so it was really pleasant to share a flat with Louis. I highly recommend this place!
