The apartment is spacious for three of us. It has the basic facilities so that we could have meals in the apartment. The location of the place is excellent for us, close to U bahn, bus routes, as well as to various museums. We enjoyed walking around the neighborhood.
When we were there, one day was 35 degrees. The apartment does not have air conditioning. It has two ceiling fans. They help but it can be hot. We needed to lower all the blinds and use all the curtains to block off light and heat. Having said that, I think most days of the year, this won't be an issue.
