Miren is really a nice host, I very appreciate her detail arrangement and helping throughout our Paris trip. She helped us to book the taxi return from/to the Airport, it is not her responsibility but she did for us.
There is one thing we didn't notice that we need to took our big luggage to go up with a very narrow spiral staircase before get up to the living area. Quite hard for girls but we did it.
Another thing, not the house problem but we didn't expect the weather is very hot only on that period especially the ceiling is constructed by the metal corrugated board with spotlight lighting with high heat gain. However, the house does not have any fan to cool down the house even at night. But this situation I believe only on the heat wave period, other time is fine.
