Great apartment. Lovely garden and surrounding area. It's a bit outside main part of London but that's ok if you want to stay somewhere nice and quiet.
Recommended for families also! Local area have great food, bar and things to do. It's a 10 min bus ride to underground.
I bought a day pass for 8 pounds which gave me unlimited access to public transport each day. You can buy it in advance for days your staying. It's cheaper than Oyster card of your only staying 1-5 days in London.
