We had a lovely stay at Kerstin's place. It's a great, quiet location with close access to direct transport, making it easy to get around the city. There are amazing places to eat and drink nearby too! The apartment is very clean and bright. The heating is a plus because we were nice and cozy every night we arrived back. There is a coffee machine (another plus!) as well as hob, microwave, kettle, etc. We didn't cook but the kitchen is well stocked for a traveller who intends to do so. Kerstin greeted us at check in and has lists prepared for travellers who want to know what to do, where to eat, etc. I would highly recommend staying here on your trip to Berlin!
