We loved staying at Andre's flat. It was really simple to get around the city from there, and it was a really calm, relaxed place to come back to at the end of the day. We also really enjoyed the heated floor in the bathroom :)
Andre gave really good, clear directions for getting to the flat and picking up the keys (with videos!), and the communication was really clear and prompt. We only met Andre and Benjamin on our last night, but I'm really glad we got to spend some time with them because they are SUCH good company and really friendly.
