Frank place is lovely, it has everything that you need for a stay with your family, everything is located close enough even if you feel like walking around more than taking public transport.
It is placed in a quiet neighbourhood slightly away from all the noise of the city central but still easy to reach it by the NCI (public transport) in about 15 min.
The daily groceries can be done from a small store but if you feel like walking 10 min, you can reach the college part where you have all your need met foodwise.
