This was an excellent flat with a super convenient location. The Paddington tube is literally across the street and is a main tube station. It's an excellent location to explore the city. Also, Paddington has an overground rail station which allowed us to head to Brighton and beyond. There are couple of markets in the station where we got some groceries. There are also a couple of small markets nearby but they are very small. There are plenty of restaurants in the area as well with many nationality choices. We had 3 adults in our group. Our adult son slept on the sofa bed which was comfy for him. The space was very efficient for that number of people. The only caution I would give is that there is construction going on from sun up to 7-8 pm(19-20) in the evening. It was hot the first few days we were there so we needed to keep the windows open. When we came home in the early evening to spend a little time before the next thing, it was difficult to have a conversation because the noise was so loud. This is not the fault of the host, although it is something to be aware of if you need to come back to the flat during the day (like to nap small children). With the weather cooling now, that may not be as much of a problem. It makes a Big difference when the windows are closed.
The WiFi was great. We could easily figure out where we needed to go with citymapper while in the flat. The hosts were very considerate and wanted our stay to be exceptional. We stayed 9 days and I would recommend this flat. We had a Marvelous time during our stay!
