Maxi's place was fine and had good response time during communication as well. The place was clean and fine, if not a little random sometimes. I'd say that it's a little overpriced, but it's in the middle of Vienna and everything is overpriced. It's within walking distance (20-30 mins) to the innerstadt (and also a rather large asian markt, if you're in to that) so overall very nicely located, which makes sense for the price. We did have an issue of the electricity going out, but we were not at home much anyway, and it was fixed when we got home, and Maxi communicated well about this. Hmm, it is a shared place so there are quite a few other guests, but only one bathroom and toilet, so the mornings/nights get a little hectic, but we were lucky we stayed with nice people and every one was kind and friendly.
Overall I'd recommend this place, the hosts are kind and responsive and you get exactly what is offered. (The kitchen is very nice!!)
