Young couple looking for accommodation in Vienna for 3 months

My name is Nathaniel Schick and I am currently studying Deutsch, taking vocal lessons and am a part of 2 Choirs here in Vienna. I have been living here for 3 months in the 18th District with my girlfriend, who is finishing up her Masters in Digital Media Management and is a copywriter. We are both very active and creative people who love meeting new people and are openminded. We are looking for an apartment close to the city center, or at the very least near an U bahn station with a kitchen, bathroom, and at least one bedroom with wireless internet. Our bathroom in our current apartment is no longer working and we need to find a new place as soon as possible. We would be looking to stay until May 6th. I look forward to hearing from you.
