Carlos Javier was an excellent host. The room is small, but everything is very clean and beside of that, it's possible to use the kitchen as well whenever you want.
The area around Holborn/Chancery lane is totally in the heart of London. Underground, supermarkets, pubs: everything can be reached within 2 minutes. Walking to the river Thames needs about 10 minutes. It's a very safe area, even at night it's no problem to get home.
