Louis was an incredibly attentive host - he sent very clear emails prior to our arrival and was always on hand if we had any questions. The flat also comes with an iPhone which guests can use while exploring, complete with full data plan, which was incredibly useful! The flat itself was in a very nice neighbourhood, close to many good restaurants and Mauerpark (home of an excellent flea market and the amazing bearpit karaoke). First class stay and attention to detail. Danke!
