My husband and I stayed here for one month, mid-March-mid-April 2019. The apartment was ideal for us. We had a very good stay here and would certainly recommend it to anyone for a short or long stay.
The apartment is a 2-minute walk to 2 tube stops, a 3-minute walk to Trafalgar Square and 10-minute walk to Westminster. You can get almost anywhere in London within 20 minutes by Tube or bus. It is situated on a quiet street a block off The Strand. The Strand is a bit seedy as there were people panhandling. Just across The Strand is Covent Garden and SOHO, where there are lots of restaurants and shops.
The apartment was comfortable. The kitchen has a full-size refrigerator with a freezer. The stove top and oven worked great. Having a few more utensils and kitchen gadgets would be helpful. The microwave heated things quickly. There is a clothes washer, but no dryer; we just hung our clothes on hangers to dry, and they dried quickly. The shower had two heat settings and two power settings, and it provided a nice strong spray. A small bath towel and small hand towel was provided for each person, but it would have been nicer if they matched. The double bed was comfortable.
Using the appliances was not intuitive, and I suggested to Alex that he provide a short how-to instruction guide for each item. For many things, you must push a red button, but the button is not always near the appliance - i.e. shower button in hall, stove/oven button on opposite wall, bedroom heater button behind curtain and drawers. We were able to figure everything out with some trial and error.
Overall, it is a very good place to stay, and I would highly recommend it.
