We had a great stay at John and Laura's place. Everything was clean and cozy, especially the fireplace. The bed was high and extremely comfortable. We arrived late at night, but we managed to get in without trouble thanks to the key locker.
The place is within a walkable distance to underground and other public transport, Little Italy district, a lot of bars and cafes. The neighborhood is quiet and safe.
Just keep in mind that it is a basement, which means you can hear people walking above you, a TV set, etc, but not late at night, so that should not be a problem.
John was really helpful, he answered all our questions quickly and helped us with our suitcases at the end of our stay, which is greatly appreciated.
