Lydia and Charles were great co-hosts! Photo in the listing are probably quite old, but sufficiently accurate. Expect wear and tear in real life (welcome to London), but everything is fairly clean and I didn't notice any mold.
Bedroom is warm, cozy, and fairly quiet but you have to close the doors to other rooms to achieve that! Wifi in the bedroom and kitchen is great. I pretty much lived in the bedroom and it was perfect for my solo, 2-week stay.
Living room has minimal insulation and soundproofing. I see one of the photo using the sofa bed. I wouldn't advise it except for heavy sleepers. The wifi extension for living room was too unstable for conference calls or gaming (though co-host said they will fix it for future guest)
Kitchen is fully functional and the professional-grade vent is great. Cookware is old, but the small non-stick pan still did the job just fine for me. (Though it's clear that inadequate cooks have left their marks over the year(s).)
