Well there must be something wrong with it, it's been on the market for months and was reduced in January.
Quite possibly a short lease, given that the listing doesn't tell you what it is (most of them do). Although Foxtons can often be very cagey about leases IME.
The square footage is smaller than my first flat, which was a one-bedroom.
The upper bedroom is very impractical, given the restricted ceiling height.
It's on a busy road, and a rat-run.
When things go wrong with those Georgian terraces, the bills are astronomical. If it's in a conservation area, or the buildings are protected, there may be major restrictions on (for example) window replacement or roof work.
There are two other flats for sale on the same road (albeit much bigger and more expensive) and another couple in similar buildings nearby. So I'm wondering if there's a big load of cross-property roof work been proposed or something, and some of the existing residents can't afford it.
There also seem to be a lot of registered businesses on that street. And I would imagine that there's something off-putting like other flats in the building being Airbnbs, or something like that.
In fact, thinking about it, I'm wondering if this flat was until recently an Airbnb, and the owner is getting shot of it. It's definitely styled like one.
