The place itself is nice, in good nick and as presented in the pictures. The kitchen is well-equipped, you've got all the home entertainment you might hope for, including a well-stocked library, and the fittings are high-quality - a little bit too much on some cases: I was unable to open the electric bedroom blind during my two-week stay because it could not be charged, requiring a remote control. A handyman was sent to fix small problems. Only real niggle was the rock-hard pillows.
The keys have to be picked up and returned at a newsagent 15 minutes' walk from the property, which may irritate you if, like me, you've got a bunch of heavy cases with you.
The area is nice: quiet and suburban, but with reasonable transport links and a cluster of nice pubs and restaurants on nearby Lordship Lane. There's a nice market nearby on Saturday mornings.
The main disappointment came in communication with the company managing the property, which were erratic, confusing and inconsistent. This was particularly problematic when an agreement to extend my stay was rescinded two days before the planned extension, the homeowner having apparently changed their mind.
If you're looking for a short, simple stay in the area, then this place is probably fine for you.
