I would highly recommend this apartment. It is big, new, with a lot of light and pretty; it has everything you need in it. We are a family of 5 people, and it was perfect for us , since we were able to cook in the spacious kitchen and that saved us a lot of money. Berlin is very big, so you need to use public transport to move around. Although we had to take a bus and the underground, as they run every ten minutes, it was worth it. We got a daily pass which was 17,30 for all of us, and we were able to go everywhere.
The family is great, they were really kind and helpful.
