We had a lovely stay at Evelina's apartment. It is in an ideal location, situated on a quiet street but only a 10 minute walk from the centre of Vienna. There is a bus stop outside and also a tram stop a few minutes walk away.
The apartment was nice and clean and had all the amenities you need if you wanted to self cater (Oven, Hob, Microwave, Fridge freezer etc). However we ate out all the time as there are plenty of bars and restaurants nearby.
The bed was really comfy and my wife and I slept well every night.
Evelina is a great host and answered emails very quickly. She even kindly arranged for a taxi to collect us from the airport and the driver handled the check-in too.
On the last day Evelina let us store our bags for an extra few hours after the scheduled checkout, which was much appreciated as we had an evening flight and it meant we could still use our last day for more sightseeing.
I'd definitely recommend Evelina's apartment to anyone visiting Vienna.
