Mathias' place was top-notch, a really beautiful house in a nice quiet area, super handy for the airport (15 min by taxi), and just a ten minute walk to the Metro (underground) station, which brings you into downtown in 20 minutes for just 2.4€. Mathias gives excellent route directions to the house and checkin instructions to the lockbox. I arrived late but I felt really independent and free by choosing my own self checkin time with the lockbox. I highly recommended, and so much nicer than staying in a corporate/tourist hotel. We loved it, thank you Mathias!
