    I have to say I was super unlucky with my roommates. 4 out of 7 were snoring without break but that's not they fault. The staff was super available and the environment friendly. It was possible to hide the bad with a courtain in case someone wanted more privacy. The position is super central and perfect to visit the city and reach the airport. I recommend it and I hope you'll have more luck than me with the people snoring 🤣

    Great hostel with very helpful and friendly staff. My only suggested improvement would be to have a place where people can hang out after hours

    Very Good

    Location is central. But Doesn’t really seem like the youth/party hostel it once was. They have a lot of long term older tenants, which I get that they had to probably pivot the model due to covid, but still. Also the description needs to be updated to explain that a lot of the benefits of staying at the hostel are gone due to covid (free breakfast, free beer, free dinner — none of it was actually offered/available). You can still be social if you try, but the hostel is not the conduit.

    Very Good

    The hostel is great in lots of ways BUT a major deep clean and declutter is urgently required. Guests need to be informed/reminded to wash up after themselves and to keep their own stuff in the dorms organised. In fairness to the cleaners it’s hard to clean a bathroom or dorm if there’s stuff strewn around the floor which might or might not belong to a guest. It’s centrally located with a relaxed friendly atmosphere. The dorms have lockers as well as a small shelf, curtains a light at each bed.

    At the first moment after my arrival I was a bit surprised what other guests were in the common area. It was mostly old Bulgarian men who seemed like they live there for long term. Of course I have nothing agains such guests, I just wouldn't expect them in a "travellers" hostel. Anyway, later I met some other international travellers and we've spent a lot of great time together. Also the staff was really helpful. Yeah the place is really not clean, but I could survive that.
