It was a wonderful time in London and staying at Helen's home added to the trip so much. A beautiful, tidy and clean house of an artist with a nice garden. Free and pleasant atmosphere and above all the kindness and lovely personality of our host. Though the location is not in the very center, getting to and from it was easy enough with the public transport, altogether taking around half an hour.
Kindly recommend to anyone wishing to have a relaxing place to stay and all the artistic souls. :)
