Host left us to do our own thing.
We don't travel very often but if we visit London again we would certainly love to stay again as it is central (Zone 2 is perfect considering Oyster Card costs max at £6.50 per day when in this Zone) and I was able via the citymaps application to figure tubes and buses very easily.
The host arranged parking for me which was a deciding factor for me on this visit.
Room has locking door and we were given key to the front door.

Couldn't ask for easier place to stay...
