Fantastic location. We stayed at Jamie's flat for 6 days. 2 adults and 2 children.
First let me say that you can't get a better location!
We walked Westminster Abbey, Buckingham Palace, London Eye and Temple area without problems.
You have 3 grocery shops within 5 min walk.
Several pubs for a nice pint and fish and chips.
His apartment has everything you need to cook your dinner and we had no problems with the amenities.
But,
Jamie's flat heats up quite a bit. We had to have the windows open and the fans going when we were in the apartment and the curtains drown when we were sightseeing. Since the flat is at a main road it is very noisy. At night, with windows closed, it was difficult to sleep.
Saying this , we would gladly stay at his Apartment again.
