But just taking off and going into the countryside is an excellent suggestion. There are several other wine regions, for example Bordeau, where you can go biking for a weekend, or simply tour several different wineries or just enjoy yourself with the locals in the countryside who are also very friendly. This is the time of year when there are not too many crowds. The city won't be in bloom, but having the city more to yourself balances this out. These deals also come up in the fall.
Summer is the most crowded time along with holidays.
And one thing to remember if you are planning ahead, August is when most of the Parisian natives go on vacation. If you go in August, you will deal with crowds, and sometimes you will not get as good of service since the Parisians themselves are taking vacation. Let the charm of the city romance you. And there is a lot of information right now there on apartment rentals in Paris, too. So check it out.
