Mirey was very welcoming and accommodating (even preparing us some fresh fruit when we arrived and sending us off on our long bus ride with a pack of cookies).
The house was very clean and comfortable.
While accessible by metro, count a 15 min walk from the Plaza Egana metro stop (but if you miss the metro, which closes on the early side, a cab from Plaza Italia will cost about 6'500).
I would stay here again.
