We stayed 5 nights in Sarah and Jan's place over the months of february 2020 and it was a great experience. The flat is perfectly located, clean and well decorated. We could enjoy some series on Netflix on both of the TVs. We also liked that there were beers in the fridge when we arrived :-) Also, everything is freshly renovated and brand new (beautiful shower).
They'll also provide you with some homemade guides of the neighborhood and the city. Their flat just made our stay perfect! I'd highly recommend their apartments. Thank you again Jan and Sarah.
