We had an amazing time in 'Innerstaedtisch, ruhig u gruen'! Organising (check-in/ out, where to get the keys etc) was really easy and relaxed. The apartment is perfectly situated too, within easy walking distance from Mitte, Alex, Mauerpark/ KastanienAllee. The place itselfis very tastefully decorated, peaceful and made us feel instantly at home. We'd definitely stay here again when we come back to Berlin!
