We only had a one night stay with Paul, but it was terrific! His flat is new and very modern, with fun touches like a pinball machine and a fridge well-stocked with beer for his guests. He was at work when we arrived, so his friend Tatiana was there to greet us, and she was super friendly and welcoming. It's very conveniently located near Kings Cross station. You might consider looking it up on an online map before you arrive, because his small street is in a gated area, and it isn't marked on some old school maps (the paper kind--remember them?).
The bedroom we rented was cozy as advertised, and we had access to a shared bathroom and a big shared living space/kitchen area/ outdoor patio space. There were some other AirBnB folks renting another bedroom in his place while we were there.
We met Paul the next morning, before heading out, and you couldn't ask to meet a nicer guy. He made us some coffee, and had fruit and croissants on hand to offer us for breakfast as well. A special note to vegetarian or vegan traveleres--Paul is a long-time vegetarian and very accommodating! My friend and I are vegan, and Paul mentioned that if we'd let him know in advance, he'd have had some other vegan breakfast options on hand for us.
Really friendly guy and a nice, modern, convenient spot. Recommended!
