After some research, Everyday Bangkok Hostel caught my attention. Here is the impression I had of the place:
One can tell, that the owner puts his heart into this place. The hostel only recently opened its doors – so everything is new. What I particularly liked about it, was the colourful décor. Bold colours everywhere you look, high ceilings, a guitar in the living room which when played well earns you a free beer (awesome!). What we loved the most, as long-term travellers: big washing machines on almost every floor (1 whole load equals 40 Baht is incredibly cheap!) and plenty of hanging space in designated outdoor areas to dry. Good thinking guys!
