A perfectly nice, basic budget hotel, our stay at Hôtel Tête d'Or probably would have been a lot more enjoyable had it not coincided with a bit of a heatwave in Lyon, with temperatures pushing 40C. The rooms didn't have air-conditioning (we didn't think to check when booking) - they were able to lend us a plug-in fan at reception downstairs, but fans are not as beneficial in the heat as air-con, and also there was only one power socket in the room into which we could plug the fan, which was right by the head of the bed! As we needed the fan on to be able to sleep, this meant having it aimed right at us from a short distance away. Also because there was only one socket we coudn't charge phones / cameras while we were in the room as we always needed the fan plugged in!
The staff were very friendly and helpful whenever we had any requests, and the continental breakfast was nice if not a bargain. The location of the hotel is a little bit away from the main tourist areas in Lyon, it is close to a Metro stop and generally things are walkable but you could certainly be closer to the main sight-seeing areas.
The hotel appeared to be undergoing renovations when we were staying - the front of the building had been updated already, but on the day we checked out, they were in the process of ripping out old wall coverings / carpets - so who knows what it will look like in the near future.
