I recommend these rooms firstly for their location: right next to the Zieglergasse subway station. The interior had a very nice and modern design, clean rooms with intelligent locks, so you don't need to worry about losing the keys (just make sure to remember the key codes or have them written somewhere handy).
Great communication with the hosts: they responded very fast to each of our questions and helped us with the transport tickets (since we are not good at German :)) ).
The only downside and the reason we didn't give 5stars is that in one of the rooms the air was really hot and we couldn't sleep properly: there are fans in every room, but in our case this wasn't enough. The hosts said they will soon install an AC, so this will fix the situation.
