The host is a company that rents the apartment through Airbnb and other means. The company provided directions regarding locating the keys and the apartment, which I found a bit confusing at first. After I located the apartment, I was very pleased to find it was spacious, clean, modern, and quiet. The building is across the street from a beautiful park, close to the Underground, and walking distance to shopping and restaurants. Coffee, shampoo, body wash, body cream, laundry soap, and dishwasher soap were all provided! (No microwave, which wasn't a problem for us.) Milosh, from the company, kindly gave us a later checkout to keep our packed bags in the apartment, as our flight left in the evening. He also saved us a trip to the company office by coming to our apartment on our last day (a Sunday) to copy my passport and take the key.
