Oliver and Raphael have a great place located very conveniently on a direct line that takes you to the city centre in less than 15 minutes; the underground metro is only about a 2-5 minute walk from their place and is quite the USP of their place.
The apartment is very spacious and can easily accommodate 3 people; the bathroom, though clean, is tiny, and, with lack of ventilation inside, can get a bit stifling; also, in the morning, there can be a lot of sunshine (even with the curtains) which is great if you are an early riser but a problem if you don’t. Also, it got a tad bit warm (in their defence, Europe is a bit warm this year and apartments do not have fans and air con).
Rest, the apartment is well equipped with everything you need and is very clean and tidy.
The apartment is strongly recommended for its location and if you can ignore some of the flaws.
