Unfortunately, I didn't meet Selma in person and my 3-day stay was quiet, once I was alone. The pictures are accurate and her house is very well equiped. I totally recommend it!
Some comments on the location: It took me about 12 minutes walking from the house to any of the stations (Alperton and Hanger Lane). I do NOT recommend arriving at Hanger Lane for first time, in the evening. There are too many exit options and different tunnels, for one that has never been there before (and people didn't help much) it might get complicated to find your way. From Alperton is much much easier!
