Lukas is a great guy! Very cool and accomodating, offered alot of help and was always available if i had any questions. The appartment is perfect, has every you need, its very spacy, tasteful and comfortable, and the location is great just a 5-6 minute walk to the metro lines which basically gives you access to the whole city, also a bus next to the building that takes you to the center. Right accross the building there is a big supermarket which was very convenient as well, also a nice cafe closeby. I would definately book it again if i am in Vienna and you should too!
