I did not plan to stay here, but managed to get a bed straightaway after calling them. Every other hostel around was booked. I stayed for one night in a four bedded female dorm with its own bathroom facilities. The hostel is in a lovely location. It is quite a way out of Haarlem city centre - to get here, get bus number 2 to Haarlem-Noord from outside Haarlem Centraal station. Outside the back of the hostel there is a canal and it is surrounded by parkland to the side of it. It is very pleasant for strolling. Its location gives it a rural feel. I was getting tired and needed somewhere quiet just to chill out for a bit, laze around, read, write postcards, stroll and enjoy the sun. It is not close by musuems, bars etc.
There were a few difficulties. There is a rule that dorms are to be quiet after 10pm in order to respect that some people may be sleeping - there is the bar and the lounge for socializing. However, I found the hostel to be VERY noisy. Its way out location means that people don't go out at night there. In addition, there is limited food for sale. There is a supermarket close by - follow the canal path to the crossroads. There is a small supermarket, pizza takeaway etc. These are not open on Sundays, so I found an even better place. Go to the end of the canal path, and look for a garage. The shop in there IS open on Sunday, but it is not advertised on the hostel notice board. It is also much cheaper than the hostel for soft drinks and sandwiches, and there is a good range of reasonably-priced gifts and books on sale. Breakfast was a good buffet selection. Internet access was available. The bar, the Shuffle, was quite relaxed.
I think it is lovely hostel in a gorgeous location, but not somewhere to go for a quiet nights sleep. My bed cost 19.50 euros, with my HI member card discount.
