Great location - we stayed at Sasha’s place as a base to re-visit London (where we lived years ago) and to go to Wimbledon. It worked excellent for both.
As mentioned, we were there during The Wimbledon Championships (which we walked to/from) - very convenient, but the nightly rate was a bit high. On-site parking was a great perk!
Sasha communicated with us very well and was there to meet us for check-in as promised.
The only other downside was the unit (kitchen & bath) should have been cleaner, but we dealt with it.
