I highly recommend staying at Dieter's airy modern flat. My husband and I stayed for a week and would have liked to stay longer. Dieter supplied everything you might need: a well stocked kitchen, very clean, light filled rooms and a super comfortable bed.
Other pluses are the lovely, romantic St. George's Garden which you pass through going to and from the Russell Square tube station. The flat is an easy walk to Exmouth Market which has a lot of fun (and good) restaurants.
We had a great visit.
