Baerbel was extremely accomodating - we needed to come and stay very last minute and she got everything organised and met us and explained how things worked and came to let us in. And she was generous and very kind throughout. We had some small trouble with the bathroom and she organised for a plumber to come immediately and came to meet the plumber and got the problem sorted out. Generally she was extremely generous. The flat itself is beautiful and the area is totally gorgeous - lots of vegan restaurants very nearby (if that's Your Thing) - and lots of beautiful squares. It's also super close to Neokoln S-bahn and U-bahn so very convenient. I unreservedly recommend staying with Baerbel - and this apartment is a Total Treat
