This is my second stay at Ernesto's place this year. Staying somewhere more than once says everything I guess :)
The location is seconds away to transport and museum's. A grocery store is in a handy location too. The place is set up really nicely and my stay was exactly what I expected - excellent.
Ernesto stayed in touch to answer any of my questions and is a top host.
I know where I'd be looking to stay if I come back to Amsterdam :)
