It's kind of a youth hostel. Every room is rented and we share the bathrooms, the kitchen and a small living room. The bed was far too small for 2 people (120cm) and we can hear trains pass near the flat very frequently (all the trains coming and going from Kings Cross Station and St Pancras International). The kitchen was okay and you can serve your breakfast with cereals and a lot of fruit.
We didn't see Ricardo and Luis a lot but the communication was very good and easy with them.
