I stayed at Henrik's apartment for five nights, and was completely happy with my experience there. The space was perfect for one person or a couple, with a good-sized bedroom, a bathroom with a tub, and a well-equipped little kitchen. It has high-ceilings, big windows, good water pressure, and was very clean. There are other nice little touches that make it homey. It's also in a great location...right between the Prenzlauer Berg/Mitte neighbourhoods, and within walking distance to good restaurants, bars and shops, as well as a U-Bahn stop. Henrik was also extremely easy to deal with...he responded to my booking request and a few other questions throughout my visit right away and was always helpful and friendly. I ended up extending my stay from three to five nights because I was enjoying myself too much to leave.
