We really liked staying at this huge flat. All rooms are rented out and the guests share two bathrooms, which worked out very well. The flat is very well situated, close to basically everything: metro, bars, restaurants, sights, etc., are all in walking distance. The location is also the cause of the only downside, depending on your room it can get quite noisy at night.
We only stayed two nights, so we didn't use any of the things provided in the flat, but a fully equipped kitchen and a washing machine are there.
The hosts were great as well, easy to communicate with and also very helpful with all kinds of questions. After checking out, I left my luggage in the flat during the day, which was no problem at all.
So we can really recommend staying at this place, but do bring earplugs if you are a light sleeper.
