I would highly recommend a stay in Peter’s beautiful apartment. For starters, the U-Bahn station is a stones throw away from the apartment and takes minutes to get into the city centre, trains run every 5-7 minutes or so and costs around €17 for unlimited travel for week. The apartment was very clean, the bed was extremely comfortable and the added bonus of having a balcony to sit outside and take everything in with a drink was amazing. If you stay here you won’t regret it, cheers.
