We stayed at Zoltan's place in Ealing in May - it was handy having a large place for six of us to stay while we were working in London.
It's a big property with lots of off street parking out front. Zoltan met us when we arrived, and gave us a thorough tour of the place - he was very friendly and helpful.
There is a large lounge, great for big groups. And LOTS of bathrooms.
The property is a little dated, and could be with a little love (especially the garden), but overall it was an enjoyable stay, and good for what we needed it for.
