I'm not sure if I can say anything differently than what the others have posted, because the general consensus is right - staying at Vesna's was a great experience! I stayed at her beautiful, immaculate home for two nights during the last part of my London trip. The bedroom was large enough for myself, but I suppose you can try and squeeze two people into it, if all you bring are backpacks (I could barely fit my two rolling luggages and a backpack in the floor space). The bed was extremely comfy! The bathroom and kitchen were quite clean, and though the breakfast was basic, it was quite delicious. The location was great: it was closest to the West Acton station, which was less than a 10 minute walk; however, there was a strike going on during my trip, so I instead used the Acton Town and the Ealing Common stations, both a 15 minute walk/bus away. Her home was also relatively close to the airport, as it took me less than 50 minutes by tube to arrive there. The neighborhood seemed to be a typical, quiet suburban place, which for me was a perfect getaway from the hustle and bustle of the city.

Vesna herself is a lovely person! She responded very quickly to my messages, and is very accommodating. I definitely recommend staying at Vesna's house when in London.
