The host Helena is lovely. This place feels like your home but with international people chilling around. The noise from the street is bearable, just wear some earplug if you are too sensitive (like you would do in any hostel). The sofa bed is nice enough, better if you have a sleeping bag to cacoon in it, but not really mandatory. You can ask anything to Helena and she'll try to make you feel comfortable.
Plus points for the All-in-One toilets
