We loved Selina, we stayed in the suite for 7 nights which was spacious and gorgeous.
I would have loved to give a 5 out of 5 but for half our stay we had to put up with dj’s playing until 2am, and 4am on one of the nights.
We asked about a room change but would have had to give up the suite, they provide earplugs but nothing can cut that noise or bass out!
My suggestion would be to stay if you want a great hostel in a great location but ask for a room that’s further away from the music, if that’s even possible.
