Although Nadja wasn't there when I arrived, she gave me clear instructions beforehand on how to pick up the key, and finding the apartment and getting the key went very smoothly. I was able to meet Nadja on my last day in Helsinki and she was very kind and friendly, and her English is perfect! The apartment itself is very lovely and comes with all the amenities you could want. It's located a bit outside of downtown Helsinki, but it is very easy to get to the center by bus or tram. There are lovely parks close to the apartment and a grocery store / shopping center nearby. Overall a great place to stay, especially if you're trying to visit Helsinki on a budget.
