What about a stay in the Loire Chateaux region just half-way between Angers and Tours ? You'll be offered a cosy 100 m2 duplex sleeping six persons in pedestrian downtown Saumur ( vicinity of horse-riding national school, castles, winecaves and vineyards ).
Also located in Northern Brittany, we simultaneously exchanged our two residences with a New -Zealand family in Auckland for a period of two months in 2014 - we fulfilled a similarly long exchange with three US families in N.Carolina and Oregon in Summer and Fall 2015. We arranged three others in Canada between August and October 2016. We put a halt to long distance travelling in 2017, decided to stay in France and so exchanged twice with an Australian family based in Corrèze and once with a British one in Quercy ( 2018 & 19 ). We swapped with Dorset ( GB ) last Summer and were just about visiting Brugges this Spring...!!
Our cottage near Paimpol in Côtes d'Armor (that we used as a base for Homelink swaps for many years ) has now been sold...!! And we are still eager to organise exchange trips though !!!!
