I had great communication with Edwin throughout the stay; he let us drop our bags off early and was very accommodating, also providing recommendations and help with trams/metros. His guesthouse is extremely central as everything was on our doorstep. A really nice and enjoyable stay in Amsterdam!
Just a note, it is on a busy street, but once the window is closed, most of the noise is drowned out and especially with earplugs.
Overall I would definitely stay here again.
