Marina is an excellent host, and I can see why she is ranked as a Superhost here on Airbnb. My friend and I stayed at Marina's place for a long weekend during what we realized after was the beginning of TIFF in Toronto. We were so lucky to find this place as it was right in our budget and centrally located to our friends and activities.
Our flight was delayed, so I was concerned we would have issues with check in, but as this is her home, Marina was super-communicative and was ready to greet us as soon as we arrived to ensure our comfort. We stayed in the King room which is in the front of the house and gets great sunlight, and had water and glasses waiting for us. She even shared some of her wine with us before we settled in! I love that Marina is a local, and offered so many suggestions on places to eat, art, and nightlife spots. Great wi-fi, amenities like a blow dryer and iron/ironing board (that apparently is not standard across the board).
She does rent other rooms in her home as well, but the other guests were quite quiet overall. There is one shared bathroom, so definitely be mindful of the time you take in the shower/toilet. That is the only reason why I did not rate 5 stars, because Marina is by far one of the best hosts I have met. She even made us pancakes on our last day! She is a gem, and you will enjoy your stay here.
