The stay at Petras house was ok. We liked the balcony and communication with Petra was super easy plus she provided us with all necessary information. Also her roommates Mel and Morton were nice.
Unfortunately, I have to deduct 2 stars. One for the appartment, that surely was a beauty in the 1950s, but since no one seems to have taken any care of it since then, I looks pretty rundown now. The paint is falling from the walls, there is a huge stain from (i guess) some earlier waterbreakthrough, not all lights work, holes in the floor etc. The second star is lost to a combination of bad WiFi, a too small bed, a cockroach in the kitchen and the fact that Petra and her roommates waste a lot energy by always leaving the lights on at night. All in all I would not recommend the place, especially if you care more about a nice appartment.
