The Séjours & Affaires is an excellent choice for longer stays in the (at least 4 days) in the Grenoble area, for example of you are working in one of the businesses based in Europole or the Presqu'ile area. It's not luxurious, as it is also used by students, and I only spoke to the reception for the first time on my final day. The bed was comfortable enough and there were 2 chairs (not always the case in budget hotels' double rooms), with a desk/work area for one person. This lacked adequate lighting, so if I wanted to read I had to sit on the bed. There's masses of wardrobe space and drawers too. There's also a kitchenette, with a slightly random collection of equipment and no coffee filter. A two ring electric hob worked fine once I worked out how to switch it on - you have to leave your finger on the button for about 5 seconds - it's a safety measure, but not explained! There's a standard sized fridge with very small freezer compartment - it's not too noisy, and also a microwave and electric kettle. Neighbours were quiet, but often had strong cooking smells (lamb?)
The TV only offers basic French language channels.
The shower/toilet was effective, but I found there was a risk of knocking the temperature control while standing in the shower, and suddenly getting scalding (or cold) water. The hot water tank is above the WC, and I managed to bang my head on it once!
It's close to a Tram stop (Cite Internationale towards Oxford on line B).
