Enjoyed our stay with Toni and James, directions sent to us were perfect and found the apartment with ease. Check-in was fast which is what we wanted, as we had our own plans and were in a rush so that accommodated us great.
Was close to Camden Market and not far at all from the tube station so that was handy. Due to our plans we didn't arrive back until 1am, was fairly quiet through out the evening and morning but the walls are quite thin.
One thing I would suggest is unplugging the fridge before you go to sleep as we found it got quite loud during the night when it kicks in.
I would also be tempted to bring another pillow next time as the 2 supplied were uncomfortable for us as quite plump and hard. A proper duvet as well would have been more comfortable for sleeping but wasn't too bad with the sheet and comforter.
We would definitely stay again next time we are in London though!
