Our stay in Leon's apartment was fantastic. Leon was kind enough to organise an airport transfer to make our trip easier. While we didn't get a chance to meet Leon he was always easy to contact and very helpful.
The apartment is clean, stylish and gorgeous. Leon really takes the BnB concept to another level, offering complimentary breakfast items, and refreshments with a selection of Austrian snacks in the minibar for a reasonable price. Plenty of maps, suggestions and tours are provided in the flat, with contact numbers & stationery available if required. The large bathtub was a godsend after the extensive walking we did throughout the city and we slept like babies in the comfortable bed.
I would highly recommend anybody thinking of visiting Vienna to stay here, as we definitely will next time we come to the city. Hands down the best experience I've had in accommodation.
