In AirBNB, having a good hearted and caring host is one of the most important things - because sometimes things do go wrong. Martin and his partner were above and beyond. I got my key broken inside the door lock on a Sunday noon, and got stuck out of the flat, while Martin was away on vacation abroad. Still - he answered immediately, took care of everything quickly, and didn’t even charge me anything! And I got the same welcoming and patient attitude with everything else that I needed. Eva, who was there to help, was also super friendly and helpful throughout my stay. Guys - I can’t thank you enough, it was so heartwarming.
Regarding the flat itself - it’s charming and lovely exactly as advertised: spacious, clean, lots of air and light, super quiet (the large windows are facing an internal courtyard with a lovely small garden), the neighborhood is peaceful and yet very central (5-7 minutes walk from the Landwer canal, restaurants, bars, etc.) and also close to main transport lines (700m from U-Schönleinstr, 600m from U-Südstern, 800m from U-Hermannplatz, M41 right at the door). In short - a super experience, warmly recommended, and I will gladly come back next time.
