If you want to visit Vienna but still feel like a local, stay at Carina & Georg's place! It's just as described in the description. The apartment is near the metro, bus, and tram so it is easy to get to the center of the city. It is in an older Austrian building (which we loved!) but that means no elevators, and given that it is on the third floor, it was a hefty climb up with all of our bags-- but a great workout for our legs!
The beds were also very comfortable. There's no AC but there are some fans so you can't even tell the difference. There are many amenities in the kitchen and there are supermarkets nearby if you choose to cool in. Everyone (especially our hosts) we're very kind. Be careful of the taxi drivers though! Our taxi driver took us to the wrong apartment at first before we had to correct him.
Other than that we had a great time. Our only regret is that we didn't stay longer!
