I only stayed at Jimmy's for one night before an early morning flight. The place is exactly as described, very charming and clean. It's a bikeable distance from both the train station and the De Pijp neighborhood. Jimmy was also really easy to get in touch with and very informative prior to my arrival. The only thing is that, as stated, it's on the top floor of the building, and if you're not familiar with Dutch stairs they can be very narrow (this is why I stored my luggage at the train station and just took an overnight bag).
