We spent 6 nights in Amboise as part of a 2 week Loire Valley trip, where the weather, at the end of Sept/early October, was consistently rainy and chilly. It is a great base for seeing lots of chateaux. The pros - it is in a quiet location a short walk up from the main town and convenient for seeing Amboise’s sites. The heating worked well, important given how damp and rainy it was. There is a washer and dryer - great for longer stays.
Alexandra was easy to reach and very friendly.
Beware - the town of Amboise is doing major road construction, and the street where the house is located will be inaccessible to cars for months, making getting luggage in and out of the house a challenge. Alexandra can give options.
The house is ancient, but has been modernized and fitted out to meet holiday needs. There were two of us - and we used the upstairs bedroom and bathroom, which were cosy. There was good lighting and lots of cupboard space. The living room was compact but fine for us. The kitchen has all the usual equipment you need to prepare your own meals.
The other bedrooms/bathrooms are downstairs from the street level, with windows on the back of the lower part of the house. There were lots of steps up and down to access.them.
Make sure to pick up supplies before you arrive - apart from coffee and basic condiments. Within a 10 minute walk there is a small grocery as well as a wonderful bakery and many restaurants.
