I will go with 4 friends next summer to London to paint there on the spot some watercolours. We are looking for nice spots, where we can sit and paint for up to 4 hours.
We are especially interested in places above the roofs of London - maybe the roof terasse of a departement store or something similar with view to a sight of London (e.g. St Pauls etc.). Are there any "hidden places" we should know about ?
Thanks for your hints ...
