If you are looking for a perfect located, well-maintained place with a really, really good hospitality - that is definitely the right place.
We had a very enjoyable and cosy stay at Dara's home with the great care and support!
We will be coming back if we have a need to stay in London, and not necessary in Wimbledon, as long Tfl service to Wimbledon is very good (in our case ~ 10 min. by South Western Railway from Vauxhall railway station).
