A very charming apartment with excellent facilities and location. Plenty of space. Easy access from the airports by bus and U-bahn. Stefan is a very service-minded host and highly recommended.
Though, our overall experience with six nights in Stefan's apartment has been lowered by annoying smoke from neighbours. Especially the ones downstairs who smoke water pipe and use enormous amounts of incense. Maybe something you must accept can happen in a big city? Certainly beyond Stefan's control, but I think other guests should know about it. As Stefan is picky about guests not to smoke or make any noise, I didn't expect it to be such a big problem the opposite way. Also we have some remarks on cleaning.
