For starters, you couldn't ask for a better location to stay in Vienna. Right across the street we had the Belvedere Castle, a tram stop, and also a Big Bus tours stop. There is also a huge fountain lined with roman columns a 5 minute walk from the house where you can hang out at the end of the day and relax. The city centre is less than 10 minutes away by tram and is quite close to the motorways as well for those coming by car. Speaking of cars, parking was surprisingly easy to find as the entire street is lined with parking spots.
The interiors of the house are absolutely spot on with a lovely sun room attached to the living room. The balcony is lovely to hang out in as well.
The only hiccup we faced was that the frame of one of the beds was a little lose which made the bed slump. However, when we informed Nicolas, he was very prompt in his response and came over within 30 minutes to fix it.
Finally, Nicolas is a lovely host, very friendly, easy to communicate with, and always available to help out if needed. I'd definitely recommend this apartment to anyone looking to stay in Vienna. We got way more than our money's worth staying here.
