Not exactly near the tube, would say it's a 10 to 15min walk to Marble Arch station. Well equipped kitchen. Can be a bit noisy at times because apartment is facing the main road. No A/C but Tim has a small fan in the room for air circulation. You can open the window if noise is not an issue. There are 2 supermarkets and a Macs across the road.
Some communication issues towards the end of our trip but overall, a decent stay.
