We (family of 4 from US) stayed in the flat for four nights in June 2015. The flat is large and comfortable, and it's very well furnished as far as bedrooms, kitchen. bathroom, laundry and other facilities.

Pros:
- Large and comfortable - we had 2 adults share the larger bedroom, one kid in the smaller bedroom, and one slept on the very large living room sofa
- Centrally located - if you want quick access to Leicester Square, Trafalgar Square, shows on Shaftsbury, and restaurants/shops, this location is great.
- The rooftop deck is amazing - great "Mary Poppins" view over the rooftops of London
- The kitchen. laundry, and bathrooms were well stocked
- There was a great house guide with recommendations for things to do in the area

Cons:
- It's a very busy neighborhood. It's located over a range of adult-oriented establishments - bars, massage parlors, sex shops. This might not be comfortable for all guests.
- More importantly, there is street noise almost 24x7. The bars are busy til 2-3 AM and trash pick up starts not long after. If the windows are open, you'll hear it.
- It was extraordinarily hot during our visit - 94F which is unheard of in London. With all doors and windows open, the flat approached 80-85F inside. With windows closed to avoid the noise, it was very uncomfortable. There's not a fan in the flat, despite my requests.
- Smaller issue but it's not easy to drop off/pick up luggage. It's a busy street and there's no good place to leave a car for 10 minutes while loading or unloading.
