We had an exceptional 1-week stay at Panus' place! Panus is a lovely family man, always available for questions (both via whatsapp or in person) and very very kind - by far the best host I've ever had through Airbnb. The rest of the staff too were very polite and helpful. We arrived late at night and self check in was really easy, Panus kindly greeted us the next morning on our way out!
The studios are located in a very convenient position where a few steps from the building there are U-bahn, tram and bus stations that connected us to literally everywhere important within 5-20 mins with very few transfers, if any. If you choose to walk to the city center it will take you around 30 minutes and you get to pick between two main streets, Mariahilfer Str. which is a pleasant pedestrian shopping street or Gumpendorfer Str. which contains lots of unique local shops and eateries. The neighbourhood itself is full of places to eat (pizza, kebab, sushi) and convenience stores (Spar, Lidl, Billa, pharmacies, DM - health and beauty store) all within a 1-5 minute walk. At the same time it is also very quiet!
The hotel itself seemed newly renovated, with very quirky and fun decor, spotlessly clean in an old but well kept Viennese building with large windows but no elevator. The studio we got was on the 3rd floor but the climb wasn't hard at all. The space was very roomy for two people with lots of storage and sitting spaces (desk, table and sofa). The bed was big and comfortable, lots of plugs to charge our devices, air conditioner, tv, a little kitchenette with literally all the amenities including a Nesspresso machine with provided coffee pods, milk and sugar. (There was also a breakfast bar on the first floor that had milk, teas, muesli, jam and fresh pastries). The bathroom was big and clean, there was hot water always, we were provided with lots of towels, soaps, shampoos, a hair dryer, bathrobes and slippers. Very nicely decorated, clean, comfortable, big bright windows.
In general I could not have asked for more from this place! I highly recommend you stay at Panus' studios - they will make a wonderful base for your trip to Vienna.
