I can only recommend to stay in this appartment. Its location is great. Supermarket, metro and restautants is very close.
We stayed 7 people in the flat. It worked out great, because we were 4 teenagers (2 of the beds are a little bit small, so I guess max 5 maybe 6 adults). The flat i spacious, and it works ok with only 1 bathroom, because the toilet is in a separate room.
We got a fantastic welcome (arriving at night) with wine, fresh bread and stuff in the fridge.
