Alfredo's place is fantastic. We were traveling with our two boys (12 and 9) there was plenty of space for all of us. There is a subway station very close for easy transportation. It is also a very close walk to many of the sights around London. There is a very nice loop around the river it hits the Tower Bridge, Borough Market, Shakespeare's Globe, Big Ben, Westminster Abbey and ride the subway back. Great day trip with lots of beautiful views and incredible food.
The apartment was exceptionally clean, easy to access, very quiet and secure. I would stay there again in a heartbeat.
