I stayed 3 nights with my younger sister, it was our first trip to Berlin. When we arrived Arne's house, we totally fell in love because everything was perfect! Getting to 5th level with heavy luggage wasn’t easy though it because ours were freaking heavy haha. But I hope you all don't worry about stairs ;)) Never worries! The place was super cleaned large sized room, bed was comfortable. Terrace and toilet and other facilities were sooooooo nice as well. I even stayed in the room quite long time rather than travel Berlin haha. Totally fell in love. Arne helped us to carry up our luggage, my check-in time was at night though, he gave many tips. It was kind of him, many thanks ;);) The best thing was I could use the place really privately. Private door, toilet, room, corridor and so on! There were a fridge, washing machine, dryer, coffee machine, microwave and so on!!! LOL, I can't stop saying good words, I highly recommend! Arne was such friendly and made us feel comfortable ;)) Glad to stay his place and meet him as well. The route to Tegel airport was super easy, I could access Berlin Centre super easy as well, there were many supermarkets around. Thank you Arne, I and my sister could make wonderful memories in Berlin. I'd love to stay again when I visit Berlin again :):)
