We were 8 people staying there during a week. Anyway, there were place for more people (maybe 10 or 11).
The penthouse is awesome!! It's a huge flat and the rooms get a lot of light. We had supermarkets really close (even a mall) and the connection with trams, buses and subway was also really good!

We had everything in the house: many dishes, glasses, cutlery and stuff for cooking... towels, sheets and so on.

The landlady, Alke, was very kind with us and she gave to us all we needed, like hair drier or iron. Even she helped us with maps and some info about the city!

The only problems we had it was that we had to cook in a portable electric stove, but Alke told me that they were about changing it for a real cooker, so it won't be a problem anymore. And the other situation we had it's that there is just one bathroom / shower and we were many people... so we had to make turns and it was quite slow.

Besides that, everything was perfect and I highly recomend this penthouse!
