Emil was friendly and welcoming. Unfortunately the room was quite dirty. I emailed him about it in the morning after arriving the night before, and he said he would have a look at it when he came back from work. We ended up finding another room (and was refunded from AirBnb). Emil was not unpleasant or unwilling to work something out - it just didn't meet our standards of what you would rent out for £40 per night.
The sheets, bedding and towels were all clean, but the rest of the place was a bit dirty. The table, the floor, the walls and the bathroom were unclean - dust, spiderweb, spots and left over stains.
The bed was large and comfortable, but other than that it was not a specifically cozy room - and you can hear people walking in the hallway and using the toilet/bathroom, so I wouldn't say it sound proof either.
