The apartment is great. Super central (very close to Holborn Station). The best part is that even though it is central, it's on a small street in a quiet courtyard, so it feel peaceful and nice when you're in the apartment.
I've stayed in a number of AirBnB's and Tommy's place was on the very upper end as far as being equipped and prepared for guests. It had a nice hotel level of attention to detail when it came to towel/sheets/etc. while still being a cool multilevel apartment in the the center of London.
