We had a great stay at nick's place. His apartment is in the centre of vienna. We are a bit older. So we had a bit of a problem with climbing the 3 stairs. Apart from this it was very quiet in the middle of town and we slept very well. We had contact by mail with Nick and he didn't respond on all our mails, but we had all the things we needed in the apartment. We can recommend a stay at nick's place
