Hostel Ani & Haakien was one of the best hostels I've stayed at so far. The value for money alone is fantastic as well as the atmosphere and friendliness of staff and those that are staying. They keep you up to date with the goings on of rotterdam and give you the finer details if you ask which I greatly appreciated. They also have the most beautiful cat but good luck getting to stroke it. There is also a small garden to sit and relax and chat with people. The rooms themselves are bright, clean and comfortable. You're provided with a locker and the toilets/showers are very nice. The kitchen facilities are great and really alllow you to make what you want or just to grab breakfast in the morning. I only stayed one night but I will definitely swing by to stay again.
