My stay at Elysia was generally good enough. I stayed in Sofia for one overnight only and my expectations weren't so high actually. I got from the hostel what I paid for. Anyway, let me say that description on Hotels.com doesn't correspond exactly to what you find on site. Hand towel (one) is free, but on demand. (In my opinion, if sth. is free, I should already find it in the bathroom)
Bath towel is payable (€1/each).
Air conditioning as well (€5/24h)
It isn't true there is a bathtub, but a shower only.
The most important thing you have to, or better, you must, mention in your room description on the website is that Elysia doesn't accept payment through bancomat or credit card, only cash (fortunately I've been authorised to pay in Euro because I had finished my Lev money). This is fundamental to know, and I don't seem having read this on your website.
Anyway, the owner welcomed me very warmly and friendly which is sth I appreciated a lot.
