The stay at Pablo's place was great, and Pablo is the host anyone would wish for.
The room was neat, comfortable and clean, with everything needed in it. The apartment is well equipped and everything that one could need on a short (or even longer) trip is there for use.
Pablo was a very attentive host; available for a talk, local tips and tricks, information and recommendations, any help needed etc., but at the same time not intrusive in any way. I had the perfect combination of feelings that I am both a guest at somebody's space while still feeling independent enough/with enough of privacy; i. e. both that special personal touch that somebody's real living place has and the privacy one would have in a hotel/some other type of rental. I would recommend Pablo as a host without any second thought, and I'd really enjoy meeting him again.
Finally, the location itself is also more than good, since it is at the very peaceful and quiet part of Kreuzberg, with the complete infrastructure needed around (good bars, bakeries, restaurants (Asian, Turkish, Italian...), small stores, one bigger shopping centre etc., while at the same time the touristically popular, lively part of Kreuzberg, with rich nightlife, is in the walking distance, just one U-Bahn stop away. Moreover, two underground lines have their stops in the immediate proximity of the apartment, so you can easily get around the whole city.
