Marco & Cris' place in London is a nice chic apartment, not too far from the city centre. The nearest bus stop is opposite the house, while the tube is a 10 minute walk (Finsbury Park - 2 or 3 stops from Kings Cross). The approach to the apartment may not be the best, but let's bear in mind you are going to stay in the house, not in the stairs/common area of the building! The house is neat, tidy and functional for a short stay, especially when you use it for just washing up and sleeping.
In summary, it's bang for the buck, go for it 👍🏻
