We stayed here for two weeks as a family - 4 adults and 1 toddler. The flat is large and well laid out, with comfortable furniture and a modern + clean design. The location is terrific. The Weflatting is responsive via text.
However, our stay was marred by super noisy construction. Even with windows closed the living/dining area was unpleasant between 8am-6pm with loud drilling and banging sounds. (What's worse, I had read about this in another review and specifically asked about it and was told "I think construction is finished". When I raised this with them upon seeing that the construction was clearly nowhere near finished, they responded by saying "We told you that we _thought_ it was finished when you asked us...".) Given it's a new building going up next nearby, I think Weflatting should invest in an extra door between the living room and study area to better block the noise. I suspect this will be a problem for most of 2023.
Other than this, we were happy with our stay.
