Great location, the studio is very clean and well maintained. It's on the ground floor so on a cloudy/rainy day, it's darker and slightly colder than outside. However, the heater is good so that will keep you warm and cozy.
My only complaint is the noise from next door, they're doing maintenance on weekdays so if you plan to sleep in, wear earplugs.
Do check out the Portobello Road Saturday market, that was my favorite.
