For me Arnie's funky high rise suited me perfectly. I knew the location that I wanted and I knew what I could afford to pay. It was a half hour walk to Covent Garden, Trafalger Square and the West End, and about the same to Brick Lane and the East End.About seven minutes walk to the Barbican or Angel Underground stops.(Tourists buy an Oyster card for your bus and Underground travel as soon as you arrive and you'll save a fortune.)
Arnie's is a charming and friendly host who knows the neighborhood well and will be happy to answer any questions. Don't think Dorchester hotel think more stopping over at a friend's place and you 'll have a great time.
Thanks Arnie.
