I stayed at Melanie's with my girlfriend for 3 nights. The room was absolutely great. Very spacious, clean and and beautiful. The tram station is literally in front of the apartment and you can reach every corner of Berlin easily if you wish. The neighborhood is so nice that we didn't even feel the need to go somewhere else for our morning coffee or late dinners. The place is packed with great restaurants and coffee shops. Also you're about 2 minutes away from a supermarket. Melanie was more than helpful with giving us advice for great places to eat out or to visit. She helped us with questions we had about the public transport and made sure we had everything we needed. Can't say anything bad about our stay there actually. Would recommend it in a heartbeat! :)
