We really enjoyed our stay at Ranja and Zika's house. Ranja is a fantastic host. When we arrived we felt so welcomed. As we were out of the house the most of the time we didn't seen them very often, but as soon as we needed some help, Ranja was here to help (Eg: print out some tickets I forgot to print before).
The room is nice. Its a small room like you have often in London. But as we could see, it was the smallest of the three rooms. And, most important: You have a cupboard for all clothes (two woman travelling). So you can store the empty suitcases on to of the cupboard and the tiny room is no problem at all.
The shared bathroom was always clean and the shower is really a gem.
For the location: I eanjoy it to stay at a qiuet place after the rush and huzzle in the center during our sightseeing. We did a lot of walk around Sherperds Bush and Hammersmith and we felt save even during our midnight walk. If you look for a lovely place for breakfast try Bill's at Hammersmith.
