I stayed over Costa's place for the New Year 2013 with friends of mine and we couldn't have been enjoying it more! The flat is very comfy and cosy, very clean, quiet et greatly located. Oval station being 3 minutes away walking, that makes a trip to central London last less than a quarter which is super cool. I'll definitely recommend Costa's place for a couple gateway or a 3-4 friends city trip in the English capital.
