First and foremost, Borislav was always so prompt to reply my messages and so polite too. Days before our check in, he sent clear, detailed instructions on how to get into the building and get the keys to the apartment. As there was no guest before and after our stay, Borislav was so kind to allow flexible check in and out timings for us. We arrived on New Year Eve and were delighted to find a bottle of prosecco from him as a gift! The apartment was just 1 min walk from a U6 station which is just one stop from Wien Westbahnhof. There was also bus stop there and it was convenient to get to places of interest by walking or by public transport. The apartment had everything we needed for a short stay and I would highly recommend anyone to stay at Borislav's apartment.
