Commuting to London

It mainly depends if you have children. I had to do that in Feb/ March. I was leaving on Monday morning with the first Eurostar and had an arrangement with my employer to work from home on Friday so I was taking the last train on Thursday night. It works, but the children will not see their mother 4 nights a week. My children are still very so that situation was not sustainable. But if yours are older and understand, why not.
