Location is very good. Apartment is big but toilette is too small (max 1.5m2) which routine tasks like showering makes complex.
There are two types of landlords. Firsts, appears personally give you some tips, answer on your questions and give you confidence that if something went wrong they will stand on your disposal. Second one (like Frederik) communicate with template messages e.g. "return key in lock box, if it is frozen contact me (we clearly stated that our check out is at 2 a.m. and he clearly stated that he is not available at that time even if we have problem to arrange taxi to airport (only public transport to airport in that period of day)). Btw, Uber and some other taxis refuses drives to airport giving advantage for more lucrative drives of people returning from night life.
Problem with dirty dishes some previous visitors left in wash machine he tried to solve with "I appreciate you start washing machine".
So, more tailored personal approach to guests is recommended.
