Riyo's place is wonderful, very clean and comfortable. Also, they provided lots of snacks, cheese, water, soft drinks, and yogurt for free, and maps of Boston area. The location is great, 3 min walk to the metro, less than 10min walk to the Centre St. where you can find some bars and restaurants, and the neighbourhood is very quiet and safe. Riyo is a very kind host, and we'd love to stay at her place again if we're to visit Boston.
