This place is a fantastic spot to stay in Ljubljana. It is right next to Dragon Bridge, and not even 5 minutes from the main Old Town area. Ten minute walk to the train station. That all being said.... I gave it 3 stars for the following reasons.
The fridge, which I definitely planned on using... did not work. I went to the place where you check in and told them, and the man at the desk basically said "well, I guess it'll have to be fixed then." No kidding... it did not get fixed. The shower had hot water... most of the time, but the pressure was so high it actually hurt the most sensitive parts of the body. The room is very small, which wasn't a problem for me being solo, but 2 people would probably be a crowd. I stayed for 3 nights.... the second night there was a terrible smell in the room that I could not figure out. It disappeared after that night, but it was bad. Lastly, the walls are not soundproof. I could hear the neighbour's snoring throughout the nights I was there.
Other than those things, the place is great for your stay in Ljubljana, and would be a great place to use as a base for seeing Ljubljana. I just wasn't impressed with the interaction with staff and the other small things. If the fridge worked, and the shower didn't feel like razorblades, I'd stay here again for sure.
