Caroline's place is brilliant. It is ideally situated for the Theatre (we went to see Hamilton, just one tube stop away) and there are loads of great restaurants and shops just minutes away. The weather was very cold when we stayed (end of March) but that just gave us an excuse to make good use of the open fire, which was lovely. The cottage has a little front garden which is great (though too cold for us to use on this occasion!) and is secluded from the street which meant it was very quiet for a place in the heart of London. On the whole, we had a great few days.
Caroline was very responsive during our stay and I would definitely look to come back when we're in this neck of the woods.
