Kim's place is simply wonderful -- big, spacious, cozy, stylish, superbly located in the heart of it all (some of the best restaurants, cafes, museums, and sights are a short walk away, 15min on foot from the Central Station). Yet, despite being so central, it's astonishingly quiet and peaceful. The bed is super comfy, the waterfall shower in the bathroom is pure delight, and because of central hot water in Rotterdam, the water was extra hot and plentiful, as was the central heating. The kitchen is well stocked with teas and coffee, and there's 2 Albert Heijn stores within 10min walk -- so you can have breakfasts and snacks at the apartment.
Kim was extremely responsive and very helpful and friendly. I'd gladly stay at her place again, and can highly recommend it! Five stars, for sure!
