To stay with Andreas was really great for us. Andreas has a big heart (especially for kids) and always a helping hand. We need to go the doctor, he helped. We need a lift, he helped. There was a problem at the house, he helped instantly! We need to stay longer(cause of an illness), he helped. If he could not help, his brother could :)
So you get lot of service!
We were in spring with Andreas, so it was really quiet and the weather was changing. I guess you get better weather in summer, but also more people.
The way to the beach is just fine, it was really quick to walk on a calm street. We walked it at least two times a day. The yard of the house is closed by a gate, so we could leave our kids (3 years and 1 year) alone and now they were safe.
Only think you should be prepared is the way to a supermarket. Takes you 15-20min by foot. A close and really good bakery and a (more expensive) mini market is 10min walk. If you don’t mind those ways as we did.
I think to stay with Andreas is good choice, if you have or if you don’t have kids.
