I only stayed briefly at Darshan's place but he was super friendly and helpful. It's a short walk from Hayes and Harlington station so easy to get to. He and his wife make a big effort to be welcoming and look after their guests.
The single bedroom has just enough space for the bed and somewhere to put your bag, but that was fine for me. I think the larger double room is sometimes available if you want more space. Great value too.
It's a family home, not an AirBnB hostel so clean and quiet.
