Sladan’s apartment is very nice and clean. It is really close to the metro - about 7-10 minutes walk and to the great Prater park. Billa shop is just 2 minutes walk on the nearest street, as well as the cafes.
If you are with heavy luggage, be prepared for the trip to the 6th floor without elevator, but it definitely worth it.
Sladan has a good collection of tea of different tastes :) for me, as for tea lover it was a big plus. Also, big plus is that you can regulate the heat like you want.
And, of course, the cat is great!
