Can’t say a bad thing about this boutique hotel; we loved our stay at Supernova Rotterdam. The room and hotel was very elegant and perfectly clean. The rooms were big with remarkably comfortable beds and good pillows. The location was great, lots of restaurants within walking distance. We felt very safe. The staff were extremely helpful, friendly and accommodating. Great laundry facilities. We loved the bike rental included in the stay. Definitely worth the more expensive price.
