We stayed at Roman's lovely place for 3 nights. Great location, with the bus stop to the Opera/Karlsplatz(10 mins) and the Naschmarkt(7 mins) right in front of the apartment. There were also bakeries and convenient store nearby if you fancy preparing your own meals.
The apartment itself is very welcoming, tastefully decorated, well equipped and most importantly clean! Though the 3 days we were there was rainy, we enjoyed cozying up with a nice cup of coffee and cake in this home away from home!
