Ali's place is great. Stayed with my parents for 4 nights, clean & spacious for 3 people. The wi-fi is not that great, only got strong signal at certain spot. The kitchen is well-equipped. Although the flat is located on the 2nd floor, there's a small lift (can fit 2 people with luggages/3 people) in the building.
It is located on a road filled with hotels, hostels, and inns. So during certain times, it might get a bit noisy. Supermarkets such as Sainsbury's, Tesco, and Marks & Spencer located within 7-10 minutes walk, as well as a wide variety of restaurants and gift shops.
