Pia's place is a shared apartment with several other young fellows. So the atmosphere is quite like in college - interesting people to grab beer with, cooking and sharing food together, and possibly also hanging out with people from different cultural backgrounds in Berlin. With that being said, as guests you will expect lots of interactions with people different from you and I find it's quite fun to get to know people on my solo traveling. Pia doesn't live in the apartment but she is responsive over texts and also people living in the apartment are also very helpful in case you need any instant help. The location is nice which is a couple min walk from metro and supermarket. I would recommend this place to budget young travelers who are looking for some different experiences!
