The self check-in is super easy with the lockbox outside, you can access the key and you only need the code to get into the apartment. This served to be very convenient after a long flight to have the check-in be so quick and easy. The apt is a quick walk from the tube too. It is a very spacious studio apartment. Easy walk to groceries and access to sites.
Hermann is also a great host and very quick with communication. Definitely recommend.
