I didn't have the pleasure to meet Nicholas, but his place was perfect for our 5 night stay in London. The flat is modern, very comfortable and provides everything you need (even adaptators!). It was my first time in Barbican and I liked very much the location in the town, the environment of the flat and the transportation facilities.
Moreover Nicholas had the thoughtfullness of providing us the first breakfast plus tea and coffee. It was so much appreciated! Definitively an host and a place I would highly recommend!
