I arrived almost an hour early, underestimating how quickly the Heathrow Express gets to nearby Paddington (just 15 mins), so I arrived earlier than expected and the flat wasn't ready - but I appreciated Vickie coming straight over to let me in, after a brief wait.
She was very friendly, and checked during my few days with a note to see if everything was okay, which I appreciated - thank you, Vickie.
As for the flat, it's fine, and nice. It's inner London, so the area's a bit down at heel, but you're close to everything and near to town, within walking distance of Paddington and the Heathrow Express, which is a plus for international tourists.
I didn't quite expect the flat to be basically the ground level off someone's personal home, which I found a bit off-putting, but that may not bother others.
The weather during most of my stay was awful, so I was at the flat a lot more than expected - it's not a place to stay in (unlikely for tourists anyway), as it's not suitable to work in, and you can hear the kids next door through the wall, as well as any noise outside, though at night it was generally quite quiet, and the bed was comfy.
Overall, sure, it's a nice flat - there are some minor things that it could do with, but Yes, I'd recommend it to others - but not if they think they'd be there a lot of the time, as I just don't think it's a place that's suitable for being in for hours at a time.
But the host is very friendly, and it's a nice place for one or even two people to stay in.
