We visited with a family of seven (pretty much all adults because the 14-year-old is probably taller than half of us). Anton & Natalia's place worked out great for our sleeping situation with the upstairs bedroom with one bed and an adjacent living room with a futon. Downstairs were two bedrooms, one with two beds and the other with one.
The bathrooms were probably the only difficulty with a decent half-bathroom upstairs (no shower), and a tiny bathroom downstairs with a shower. Ultimately it was not an issue, we just had to stagger our schedules to make it work! I think this is an excellent place located in a fantastic location (we found something to do nearby within walking distance each day). Especially if all you plan to do is to return to sleep and not hang out too long here. We also ran into a minor issue with the hosts but they responded graciously and fixed the problem, they've been quick to respond from the get-go.
Parking options are also plentiful - we only had a rental car for one of the three nights and the hosts explained each one.
