I will start by saying we had to end our stay early due to mice in the kitchen-lounge.
Initially, the property appeared to be clean & reasonably well equipped. However the bathroom in the property is not the one shown in the listing- there is no bath in the flat, only a shower. The 'dryer' is a heated clothes airer, not a tumble dryer. The freezer was frozen shut, and when we managed to open it, the front of the freezer was fully iced up, so we were not able to open the drawers. Martin's support team suggested I defrost the freezer myself- I can only assume they have never defrosted a freezer & don't appreciate what a big, messy job this is. They said they would get back to me about the other issues but never did.
Please be aware that the front door to the flat is on the first floor, but you go up a flight of stairs as soon as you enter the flat. At the top of these stairs (2nd floor) is the double bedroom and bathroom, then there are more stairs up to the twin bedroom & kitchen-lounge. I specifically asked what floor the flat was on before we arrived, as I had a broken ankle. I was told be Martin's team it was on the first floor. No mention was made of the internal stairs (this may be a concern if you have children sleeping in the twin room needing to get up in the night).
There is a bus stop 3 minutes walk away with buses to central London, and lots of restaurants & shops close by. The Internet was fast & reliable.
