Rob's place was a great home base for the few days we spent in Amsterdam! The location was super walkable and close to everything, and the space was comfortable. There was construction happening downstairs, but it wasn't an issue (not loud or messy).
Like other reviews say, be aware that the stairs up to the apartment are very steep and tight. If you can't carry your bags up and down, it might be best to look for somewhere else. Otherwise, I'd totally recommend this as an affordable option in Amsterdam!
