Nicolai is a great host & makes sure to provide you everything you need for a comfortable stay at his place. It's well-situated just 5 minutes away from the Metro station (which is only 2-3 stops from the city center) & 17 minutes from the airport. His WiFi works perfectly too; this was important to me as I work wherever I'm at from my laptop. He is also very quick to respond to whatever you message him. Thanks Nicolai :)
