We really enjoyed our 4 days in Vienna at Maryna's apartment. On arrival, we had a good meet & greet to explain all the necessities of the apartment and POIs within walking distance (transit, grocer, restaurants, etc.). The flat was presented spotless and has a nice decor.
We arrived the third week of July, so it was very hot. I needed to ask Maryna to bring another fan as the top bedroom gets very hot. Her response was immediate! In my opinion the 2 bedrooms and living room could even use a third fan - as the advert accurately mentions no air conditioning unit.
The apartment windows don't have security bars so if you're concerned about security be mindful about keeping them open (particularly at night during the summer).
The ground floor shower is awesome! However, there are some issues with the upstairs plumbing causing loud noises from other fixtures whener the WC is used (perhaps a ventilation issue).
Residence has a variety of useful appliances and they work very well. There's a good Nespresso machine, which was supplied with a good stock of cups.
Overall, we had a very enjoyable stay here. Maryna is an excellent host!
