I cannot say enough good things about my experience at Till's place. Staying for three weeks was not enough, and I would have extended for another few weeks if I could. The apartment is absolutely gorgeous. The natural light was a dream. The bed and sheets are super comfortable. Tons and tons of space. The balconies (particularly the front-facing one) were a great place to have a glass of wine or a quick lunch or even work from home. The apartment is in the perfect neighborhood with tons of good restaurants, coffee shops, and natural wine bars. Everything you could need within a few minutes' walk. Till was also very responsive and friendly. Highly recommend Till's place if you're in Berlin!
