Great experience, super-friendly receptionists, wonderful location (next to the main station)! The bathrooms and toilets were shared and had a rather "public" feeling to them (unfortunately), but I guess that's not too unexpected from a hostel. The biggest gripe (for me personally) was the quite unstable and slow wi-fi: 18 Mbps down and 1 Mbps up with constant disconnects. Still usable to some degree but I'd prefer a wi-fi that's better than my mobile data.
Checking in and out was smooth as can be and leaving our luggage wasn't an issue at all either. Would definitely recommend and stay again. Thank you very much!
