Staying with Julia and Matthias was one of the most wonderful experiences I have had in Europe. They were so welcoming and friendly and the room/apartment was absolutely beautiful. We were greeted with fresh coffee and tea in the mornings and the offer of joining them for dinner in the evenings. The bed was extremely comfortable and the wifi was fast. The street it was located on was great for shopping and only a short walk from two underground stations. I 100% recommend staying here. :)
