hi Gartxi :)

Welcome to OpenStreetMap :)
I wanted to add that if you would like to create a map with personal points/bookmarks, you can use https://umap.openstreetmap.fr/en/ Please remember to save the editing url, otherwise you might lose access to the map you created. 

Hope you had a nice time on the island of Lesvos and thanks for contributing to OpenStreetMap :)
