My sister and I had a lovely stay at Lalith's studio. It's small but really cosy and absolutely enough for two people. Once you know your way around you can easily reach it by taking the Jubilee Line or even by bus if you like to see a bit of that part of London.
Lalith was really welcoming and was open for any questions and gladly helped us out with everything there was to know about everything in and around the studio.
If you don't mind being a bit out of the central of London (zone 5) I can really recommend staying at Lalith's.
