I stayed in Dan's studio flat for six weeks during a uni placement.
The flat is in a great location, being about 15 minutes walk from South Ealing Tube station, from which it's a half-an-hour-ish tube ride into London. I mainly commuted to and from Reading, which was a reasonable drive, and there was plenty of space to store my car on the driveway. There is a Co-Op nearby and a nice pub just along the road. It's also very near to Heathrow if you're flying to there, but London City was a bit of a trek.
The flat is perfectly sized for one or two people, and had everything I needed for my stay. If you stay for several weeks like me there is also a cleaner who comes once every two weeks. There isn't a washing machine in the flat, but that isn't an issue as Dan's partner was able to sort out washing for me when I needed it. There is however a TV, which isn't pictured, but was very much appreciated. The Wi-Fi is also excellent.
Dan and Camilla were lovely hosts, and helped me with getting around for the first few weeks. They were quick to respond to any queries, and kept in good contact about things like when the cleaner was coming. I wholeheartedly recommend their flat to anyone who is looking for somewhere to stay outside the centre of London.
