If you're going to Vienna and Erk's place is available, then your search is over. This is simply one of the best experiences you will ever have on Airbnb. The bedroom is the perfect size for 1-2 people with a very nice and very clean bathroom and the flat is perfectly located. The neighborhood is very safe and very quiet, there is a tram stop on the same block or the U-Bahn is a 6-7 minute walk that will take you to the city center in 10 minutes, and there is a great affordable restaurant and a very nice beer bar close by. But perhaps the best thing about this flat is Erk. He is very kind, thoughtful, and wonderfully hospitable and even will make you a delicious breakfast in the morning! He has great local guides and tips and will happily help you plan your days to maximize your time in Vienna. 5 stars isn't nearly enough for this place - it's an exceptional experience!
