I would say that our stay at Ulli & Günther's was probably the best airbnb experience we have had so far. Both have been very kind to us, friendly, truly professional in the same time and extremely willing to help us with any issue it might have occurred. Prompt to their responses, spot-on to their recommendations and suggestions and quite generous with chocolates :) the apartment is simply amazing; very clean, modern, well-equipped and located in a very convenient place where public transport and shops are nearby. By tram the city centre is easily accessible within 10-15mins and all the above are offered in a good value for money. Absolutely recommended! Needless to mention that if we visit Vienna again, Ulli & Günther's place would be our first priority without any second thought. Thank you very much for everything, once again!
