I have been staying at the different Astor hostels scattered across London for the last 4 years and can say that the standards of service offered by the this chain have been deteriorating year over year. 6-bedroom rooms tend to be way too small to accommodate 6 people comfortably enough. I understand one should not expect a 5-star hotel accommodation facilities, but come on! Small improvements should not be too costly to implement and would make guests' stay at the hostel much more pleasant.
I have always had good experiences when booking with The Wombats chain in various cities in Europe. Its hostels offer great facilities and are run very efficiently. Magnetic-card keys and lockers make one feel very secure. The rooms tend to be spacious enough and the en-suite rooms are maintained clean throughout. Other facilities include individual bed lamps, sockets and lockers for each bed. Public spaces are very comfortable, offering free internet connection and comfy couches.
A pleasant hostel to stay at. Meticulously clean and very comfortable. Only disadvantage is that is a 15-mins walk away from the Old Town Centre.
The Wombats Chain is the ideal hostel-like accommodation. It combines efficient modern facilities and great attention to detail. They are housed in modern builidings, which are maintained clean at every corner. The Laundry Room and machines in the Vienna Wombat were impeccable and the Card Key-controlled Lockers a confident place to store one's valuables. The Staff are always very helpful and common rooms create an incredible ambience for meeting other people.
