Overall a decent place to stay. Definitely could fit 3 comfortably, 4 might be a stretch. The apartment was clean and check-in was relatively easy, the biggest downside is definitely the location. The area is very dead at night, and it was hard to find places to eat after 8pm, even on Friday and Saturday night. The U4 is a 10min walk and U1 20+ min walking. Not sure if this apartment is worth the price point as there were similarly priced places in significantly better spots. Overall, Vienna was amazing as always, but this unfortunately had not been my favorite stay.
