Ray was extremely helpful, a great host. The apartment is very basic, but very clean and well located, and excellent value.
A couple of things to be aware of: kitchen is limited, it is quite difficult to cook anything but basic meals, as there is nowhere to chop ingredients. The heating is permanently on, as there are hot water pipes running through the apartment. This makes the apartment horribly hot (especially the bathroom, which is like a sauna), so you have to leave a window open at night, which opens onto the street.
All in all, an excellent host (5*) and a very good value, basic apartment, with a couple of minor issues (3*), so a 4* review, but I would stay again.
