It does look spacious, more spacious than some rowhomes I've seen and it has a bigger closet than a master bedroom in my suburban house! It is definitely perfect for the retired couple or a young working couple without kids. It will be tough to live there with kids because they need access to other child friendly amenities and especially to other kids their age, which might be tough to find in the marina setting. Great choice for the vacation property though if you can afford the price plus the expensive marina fees.
Most Luxury houseboats aren't really very mobile as they're hooked up to electric and sewer lines, and have no propulsion system. They need a another boat to haul them if you do need to move them.
My sister and family live on one (in Seattle) and several of their neighbors have kids. The kids have plenty of nearby places to play, and they all learned to swim at a very early age. It wouldn't be my choice, but it can be very family friendly.
