The flat is very well located in the nice St John's Wood area, 5mins from the tube (Jubilee Line) and at walking distance from Regent's Park.
Josh wasn't at home when I came, but had made arrangements for me to get the key. Unfortunately the porter had forgotten about it, but when I notified Josh it was quickly fixed.
2 other rooms in the flat were occupied by longer term tenants that I only briefly crossed.
Josh was flexible on the time to leave the flat and I could pick up my luggage late afternoon.
