Good things: Julia is a nice host and takes care of your needs. The house is kept clean. Very close to the metro station and it is a living neighbourhood, so you can have dinner/beers around. Comfortable bed and quiet in the night.
Not so good things: There are many people living in the house and I had no idea (maybe was written somewhere and I didn't realize). The house is big so there is often no problem, but occasionally the kitchen is a bit dirty. Also, since people don't stay long in the house they may take what isn't theirs from the fridge.
