We could not meet Nico.
But his feedback is very quick and helped things for us.
We arrived at Prague before noon, and had big bags. He arranged that his mother wait for us. So we could check in earlier.
It takes more and less 30 min from house to almost touristic place.
There were 2 rooms. But It looks like the apartment is only for guests.
The room and bathroom was very clean. It looks like that it just have finished remodeling.
Wifi did not work at first. But he fixed as soon as we let him know .
