We loved staying in this sweet flat. It was nice to be so close to Barons Court tube station, which has the Piccadilly and District/Circle lines, making access to main attractions fast and simple. The neighborhood also had quite a few nice places to get a bite to eat. Our favorite was the little C'est Ici coffee shop, right by the station. They had hearty sandwiches, pastries, good coffee, and some nice outdoor seating in the back. So convenient to grab a breakfast sandwich on our out in the morning! There was also a street about 5 min walk away that had a lot of restaurants and food shops (Tesco, Co-Op, Waitrose, as well as small grocers).
The flat was well-appointed, with all the kitchen items we needed, as well as a fan (it was quite hot and humid while we were in London) and a bathtub. It was also nice to be able to open the windows to get a cross-draft. We did miss having a freezer because it was hot while we were there, but in most cases, we wouldn't have missed that at all. The tropical weather was a rarity!
Mia was extremely responsive and helpful, giving us advice about the best way to get to places. While we were there, there was some kind of city-wide wi-fi issue and she was responsive in explaining what was going on.
The only con I can think of was the noise, which is not something anyone can control. The flat is right next to the front door, so we heard the door slam every time someone came in or went out. But it's hard to avoid noise in a big city like London.
All in all, it was a great experience. We would stay there again.
