Bielka's place was great! Clean, organized and well located. The bed was comfortable and the amenities very useful. Internet goes up to 12Mbps, but depending on the work you do it's probably enough.
Bielka was responsible and extremely friendly, just what you would expect from a great host.
The area is full of restaurants, bars and things to do. It's also close to many monuments and important places in Madrid.
We had a great stay and definitely recommend her apartment.
