Katerina place is very close to public transportation. To reach the place you just need to go with Metro B and continue with bus 201 to Jordanska. The bus stop only 50m from Katerina's place. I'll recommend to buy transportation pass ticket during your stay in Vienna because Katerina's place is not at the city center, so having 48 or 72 hours pass ticket is a must. The room is super clean and stylist, there is also microwave, refrigerator, and water boiler to be used by everyone who stay there. The ammenities are super complete and we really enjoy our stay there :)
