Great communication prior to arrival, and so much useful information pre-trip and on arrival. Victor is very personable - you can tell that it is not a chore to him being a host. Then he just leaves you to get on with your stay but is always available if you have questions.
As for the apartment, it's perfect for a couple of people, and you can tell it is being regularly maintained. Didn't use the air con once even in June.
Nueva Numancia itself is close enough to Madrid centro, but was not an undesirable area anyway. People on the streets until very late but it feels safe.
Thoroughly satisfied with our choice!
