    I stayed at Hostel Mostel for 2 days and it was the best experience. I don't think I would've enjoyed Sofia if it wasn't for the people I met at this Hostel. Everyone felt so warm and nice. I made a ton of friends from all around the world! I would definitely stay there again!

    During these difficult Corona times the Mostel Hostel has a really cool historic building and the staff were really funny. A lot of cool characters were staying around in Sofia. It is the coolest place ever. You can get a tram from Mostel to the foot of the mountain and you are a few minutes from the tourist center and all the bars.

    Very Good

    An okay hostel to stay for a few nights. Staff are friendly and helpful but are on reduced hours given the situation, so they're not always around. Beds are comfy & have curtains; they have personal lockers (but need to be bigger) and a smaller valuables locker in the bunk. The main negative is that the hostel isn't cleaned daily, more like every 2/3 days so the shared facilities get quite dirty. Given the current situation they should be cleaning more than usual, not less.

    Very Good

    This hostel would be great in non-covid times but my recent stay was a bit disappointing. Firstly, none of the fun free stuff applies due to covid restrictions so the hostel description is quite misleading - this should be updated. Secondly, our private room was in a separate building to the hostel which wasn't clear from the description and, although overall the apartment was nice, the bath/shower had a huge crack in it and didn't contain water.

    I would not stay here again. The private rooms are quite far (5-10 minutes walk) from the main reception and dorms, so forget mingling with other travelers. Checkin hours are reduced and when I called one of the guys about checkout times on the phone he was so rude. Location meh, a few blocks away from Vitosha street, could be better. The private rooms are not really clean and need a makeover. I recommend you find a b&b instead.

    Management is not as good as it should be, not serious about Covid19. Guests are using the kitchen and not cleaning after themselves because manager and stuff are not good enough to tell them, Excalibo is putting his own music and loud without considering the guests, he also targets every new girl, this place is too loud for relaxing, not listening to guests and their wishes, nice place but in the wrong hands, fridge is not working. I won't recommended this place.

    I do not recommend it.dirty.I reserved a shared room, where a guy harassed me inside the room, I was alone. I had a terrible experience. I informed the reception about what happened, with anguish, but they did not take the degenerate that night. The next day the man at the reception asked me why I had that face (I cried all night), if those things didn't happen in my country! it is real?2021 and asking those questions? If these things happen in my country, should I take it naturally? Terrible
