My girlfriend and I stayed at Ali's place for a week during our stay in London. The flat is very much as advertised and pictured in the listing, and like other reviewers have remarked, quite spacious and larger than it appears in the photos. The place is on the top floor of a 5 story building (there's an elevator), seemed newly remodeled and painted when we stayed there and is bright throughout the day, especially in the bedroom (during sunny days at least, but remember, this is London). The location is also fantastic, a 5 minute walk from beautiful Kensington Gardens, a short walk from the shopping area on Queensway and the 2 tube stations there, Queensway and Bayswater, and not too far from the super charming Notting Hill area. Ali and his staff were very responsive when we had a couple of issues and the check-in and check-out process were a breeze.
The only issues we had with this flat, and they were relatively minor, is that it was pretty spartan and utilitarian, essentially as shown in the photos - a bed, couch, dining table and chairs, basic kitchen items and appliances, and good smart TV and internet. We also had a bit of an issue with the LED lighting being a bit too bright for our taste, but were able to easily resolve that during our stay.
All in all, we enjoyed our stay there, and if you're looking for a basic, nice, spacious, bright flat in a fantastic location and at a very good price for the area, we can definitely recommend Ali's place.
