This place is located very close to the Wien Mitte terminal, making it a cinch to use public transit to travel in Vienna. Parking is provided at 11 Eur a day, so I'd not recommend it, esp. since it's not right in front of the property. There's a lot of shops, restaurants and grocery stores right next to it, which is really convenient to walk around in the neighbourhood. It's part of Mercure hotel, so that might throw you off a bit, but just walk up to the front desk and they'll take care of you. Getting to our apartment involved elevator access plus some stairs, so be aware of that in case you have elderly or differently-abled people in your group.
There's a small fridge and an electric kettle, but no stove, so don't plan on doing any cooking. The air conditioning was a big help during July.
Tip: buy one of the Wiener Lienen passes (24/48/72hr) (or a Vienna Card) and enjoy travel on all the various forms of transit in Vienna (doesn't included airport trains)!
