We spent 2 nights in the apartment, we had a good time, everything as promised. The apartment has 3 large bedrooms and 2 large bathrooms, it was perfect and comfortable for us (5 people/guest). The flat was very clean, and the sleeping mattress had good quality.
The place is very well located, in the centre of the city, within walking distance to everything, 10 minutes walk from e.g. Stephansplatz, Hofburg, U3, U4, U1 metro lines.
Joseph is very nice and helpful person, he provided us parking places for our cars. He is a great host, he was there in time and was available when needed, he always replied quickly.
I recommend this apartment!
