Toulouse

Here's an ideal itinerary for 3 days in Toulouse:

Day 1:

• Morning: Start your day with a visit to the Basilique Saint-Sernin, a UNESCO World Heritage Site and one of the largest Romanesque churches in Europe. Admission is free.
• Afternoon: Head to the Jardin des Plantes, a beautiful botanical garden that's also free to enter. Take a stroll through the gardens and enjoy the peaceful atmosphere.
• Evening: For dinner, head to Le Bibent, a brasserie that serves traditional French cuisine at affordable prices.

Day 2:

• Morning: Visit the Musée des Augustins, a fine arts museum housed in a former Augustinian monastery. Admission is free on the first Sunday of every month, or you can purchase a ticket for €5.
• Afternoon: Take a walk along the Canal du Midi, a UNESCO World Heritage Site that stretches from Toulouse to the Mediterranean. You can rent a bike or a boat if you want to explore further.
• Evening: For dinner, head to Chez Emile, a cozy bistro that serves hearty, traditional French dishes at reasonable prices.

Day 3:

• Morning: Visit the Cité de l'Espace, a space museum and theme park that's perfect for families. Admission is €21 for adults, but there are discounts available for students and children.
• Afternoon: Take a stroll through the historic center of Toulouse, known as the "Pink City" for its distinctive pink brick buildings. Don't miss the Place du Capitole, the city's main square.
• Evening: For dinner, head to Le Bon Vivre, a casual restaurant that serves delicious French cuisine at affordable prices.

As for accommodation, I recommend staying at the Hotel Ibis Budget Toulouse Centre Gare, which offers clean and comfortable rooms at a reasonable price. And for breakfast, you can grab a croissant and coffee at any of the local bakeries for just a few euros.
