Messaged the host before booking and he was very responsive, kind and helpful.
The room was spacious and clean, also the decoration and plants really helped to make it felt like home. Since I had booked for a month, when I checked-in I was offered weekly cleaning for an extra cost.
The flat is well located to transports, markets, restaurants, and pubs so you might not need a kitchen if you are not staying for long.
The only not so positive thing is that Clerkenwell road might be a bit noisy at night (even though that wasn't really a problem for me).
