Isa is a very nice person. You can ask her about everything and she will be happy to support you. She does hae some house rules I needed to get used to but that was a minor issue.
The room is small but exactly as advertised. I was there for 6 weeks, for the purpose of staying the night its is more than sufficient. The place is not right in the center but also not too far away. You're there quickly with public transport. Overall a very nice experience. You do need to get used to the noise though. There is a busy street by the house and the walls are thin. If you are sensitive in this regard some earbuds would do :)
