We booked for a 4 day weekend and had a great family time with access to the sea for the long walks we enjoy. Traveling with our 6 months old, we were fortunate that Michan offered so many amenities such as a pack n play, a spacious bed and bedroom, a couple board games as well as a ninja to blend our baby's food, and spices for our dinner. We were also welcomed with a quality pack of coffee and a heated apartment, right before the snow storm hit.
Don't forget your flip flops or sleepers. The tiles are very cold (maybe great in the summer) ;-)
I didn't need internet but the connection was good enough for what my husband needed it for (Skype conversations ). Phone reception is ok too.
For groceries we used instacart and ordered food. Just bear in mind that you won't find anything within less than a 5 minute drive except one restaurant as far as I know.
Whenever we needed help there was someone available.
