Our family of 5 spent the last 10 days in Naomi's home. The house was very nice, and looked just like the pictures. The beds were very comfortable and we enjoyed the space, the location, and the local food.
There is no air conditioning, so please take note before booking, if staying in the summer. We had all the windows open and during the day it was quite miserable. At night, the master bedroom never would cool down, but the breeze in the other two bedrooms were fine. Also because there is no air conditioning, and the windows needed to be open, it was quite loud. There were a number of parties and a lot of music played late into the night. About 6 days in they did send us fans and that helped immensely.
The neighborhood is right on the Bakerloo line. It takes 5-7 minutes to walk to the line. To get from Kensal Green to Piccadilly takes about 30 minutes. We saw a lot of buses but we never did take one.
There is a small grocery store just a block away and the owners very nice. We ate at the Thai restaurant and it was very good. We loved the Crazy Baker, the food was good and a great price for breakfast. Lastly, The Mason's Arms pub was our favorite. The food was good, as well as the atmosphere and drinks. We went there a number of times.
One thing to note, this is an area that appears to be going through a revitalization. During the day there were plenty of families about, but at night it was a bit of a different story. The main road has a number of bars and restaurants with many people hanging out in front. We saw a number of drug deals, and there were always teens smoking pot in front of the youth hostel and in the park at night. We never felt unsafe but it definitely had some aspects in the evening that seemed questionable.
We would not hesitate to stay here again if traveling with a large group and think you will find it satisfactory for your stay.
