Hi,
I will list what I feel I can do and what I cannot do.
1) Map has to show the bookmark with position of a specific holiday house called “Gino e Maria”.
*** Can be done ***
2) Map has to show the label “Gino and Maria” on the position.
*** Can be done ***
3) Map has not to show competitors.
*** Can be done ***
4) Map has to show other point of interest like area names, town name, beaches, etc.
*** Can be done ***
5) Map has to show the zoom button in order to allow the users to zoom the map.
*** Can be done ***
6) All this needs have to work properly in all main browsers.
*** Chrome, Firefox, Edge is confident, explorer not sure, hopefully no issues with IE ***
7) The map has, of course, to be responsive.
*** Can be done ***
