I had an excellent stay at the Oasis. The location is great for exploring Vienna (Metro station is 2 mins walk) and there are lots of nice cafes and restaurants in the local area. There are two supermarkets within easy reach, plus a pharmacy and two bakeries to pick up breakfast in the morning. The flat itself is huge for a one bed and full of light, yes it was warm, but easily ventilated by opening the windows or the door to the little terrace. It is a climb up the staircase to the 4th floor but I travelled light and enjoyed the challenge after a day of walking around Vienna!

The arrival instructions were clear and Andre's communication was prompt. The flat was very clean and is decorated nicely with lots of plants. He checked in that everything was ok with the flat and to offer local advice on my second day, which was really nice.
I would definitely book this place again and recommend it to others, it was brilliant.
