Misha is really nice, she helped me with all the information I needed to arrive in Dublin and in the appartment: even if she wasn't going to be here during my stay, she answered all my questions! Moreover, her roommate is really nice and welcoming. You can trust both of them for the deposit for the keys! I would recommend this place, but don't forget to bring your indoor shoes as the floor is a bit durty and be prepared to share a very little room and an appartment with no window with other people ;).
