This is great place to stay, especially for such a price, in central London.
The transport was quite convenient--bus stop is just outside the entrance of the house. However, transport system in London is generally confusing, especially for foreigners. So I highly suggest you to carefully study the route before the travel, (even for a transport 'expert' like me😂) and always contact the host when in trouble. There are also a couple of good restaurants and cafes, and a large TESCO supermarket around the building.
The house was quite nice and extremely tidy. Pierre cleans the rooms everyday, so everything is in good condition. Breakfast is better than expected, for the variety and quality of food provided.
Pierre is an outstanding host who can answer almost all the questions. I even interviewed him for my school project. He always care about his guests, and tries hard to make us feel like home. We talked a lot, which have made this stay interesting and comfortable.
In short, this was a great experience, and I would highly recommend this apartment, especially to people who want to understand London and lifestyles of Londoners.
