This is a really beautiful house and is exactly as described. It is large and stylishly furnished and has lovely touches such as full sized soaps and extra towels. It's in a gorgeous suburban area and has the underground, buses and a few restaurants and supermarket about 10 min walk away. It is immaculately clean and the beds are large and comfortable. Everything is there that you could possibly need.
A little advice to future travellers though is to read the house's website. There is no paper (hard copy) explanation of the house and everything is very high tech. The door opening system, the wifi and the lights all have their own special requirements. There are 4 different types of light switches so if you are entering at night and don't know how to turn them on you may be in trouble.
The stairs are mentioned on the website, but be aware there are plenty of fairly steep narrow stairs, but they are carpeted and have strong railings so if you need extra support then you will be fine.
