I was very happy with how clean and spacious the appartment was. It's got a modern in design and you have all the amenities you could require when travelling, a hot shower and very comfortable beds!. We were a group of four people and we had plenty of space for all of us and our luggage. The appartment is located very close to a large parking house and U-Bahn entrance so you can travel around the city with ease. Guido was also very responsive when we asked for assistance and instructions on how to get inside the appartment. I recommend the appartment to anyone who wants to visit Vienna, be it a short or long stay!
