Good things:
We had a good stay at Iradj's flat. It's like 30 min away from London central landmarks. It's located in the metro zone 3 in London. It's easy to catch the subway, around 5 min walk. There are a lot of stores, restaurants (fast foods), coffee shops and supermarkets around.
We didn't get the chance to meet Iradj, but the things I asked him he answered properly.
The bed is very comfortable. The heater of the apartment works really good.
Bad things:
1) the TV mutes out of the blue. It was necessary to turn it off and wait some time in order to make the sound work back again.
2) poor internet WiFi signal. I didn't know where the signal was coming from, but it wasn't from the apartment. I didn't see any router around.
3) curtains didn't block sunlight properly.
