Maria's place was wonderful to stay in! Super central to all of the main tourist sites, yet on a quiet street, perfect for resting after a busy day of site-seeing. It was also close to coffee shops, restaurants, and cafes. Our favorite breakfast spot was House of Small Wonder, just around the corner from the performing arts center (5 minute walk). Super easy to get to from the airport as the bus drops you off very close to the apartment building. The train is also a 5 minute walk away.
Maria was a great host, always available for questions and had a great list of suggestions to enjoy the city. Although we didn't spend too much time in the apartment during the day, we spent evenings there. It was very comfortable and clean. Loved the tub in the bathroom. Perfect for soaking after a long day of walking around the city. There's a Lush Cosmetics nearby that is great for grabbing a few bath bombs to take the relaxing to the next level. The internet speed was in and out, so maybe not the best for a work-related stay. However, we appreciated having enough internet to post to Instagram but not enough that we were glued to our phones all of the time. We did not cook at all during our stay, but the kitchen is definitely equipped for it.
Overall, we had an amazing stay and would want to stay here again next time we find ourselves in Berlin.
