Jerome and Caroline were lovely, with great communication while I was on my way to Vienna. The flat is incredibly easy to find as it's so close to Meidling station. I was only there for one night, but everything was totally as described and very straightforward. I didn't need to contact Jerome and Caroline while I was there, but they live only one floor above and I got the impression they would have been very quick to help if there had been any issues. Definitely recommended if you're looking for somewhere smallish and convenient.
