"We are optimistic that visitor numbers will pick up, even if it will likely be local tourists who visit the monument in the first weeks," Klahr said.
The tower's director told AP that he hopes access will be back to normal by August.
A stringent cleaning operation is in place and will continue daily from next week.
"There is a new protocol," said Eiffel Tower hygiene consultant Alain Miralles. "The day cleaning teams will be able to clean all the points of contact every two hours, from the opening of the site to its closing,"
Tourists planning trips to the City of Light are advised to book tickets to visit the Eiffel Tower online once the ticket office reopens.
Paris tourism officials have expressed muted optimism about the city's re-emergence as a travel destination.
Since confinement measures were imposed in March, tourism levels have dropped by around 80 per cent compared to the same month in previous years, they say.
"To visit Paris now is quite exceptional, as we of course don't have many visitors and we don't expect this summer to be at the same level as previous ones," Corinne Menegaux, the director of Paris's businesses and tourism office, said.
Hotel owners are also keen to welcome visitors again, if realistic about the challenges ahead - and the competition among European countries to draw tourists back in the coronavirus era.
"Everyone is Europe is looking to draw the European clientele. The Italians want to bring in the French, the Germans want to attract the Danes," said Serge Cachan, president of France's Astotel Group.
He pointed out the plexiglass protections in the reception area of one of his hotels and arrows to ensure social distancing.
He welcomed the French President's decision to let Paris restaurants reopen earlier than planned. "Without restaurants, there is no conviviality, there is no tourism, there are no clients in hotels," he said.
"The message I would like to on-pass to the city of Paris is: Hurry and open up all of the tourist attractions and activities."
