This apartment is conveniently located near the train station. The accommodations are tight and simple (a room with 2-3 other people in the apartment), but that's reasonable for the cost. Unfortunately it was not kept clean, and my feet turned black just a few minutes after walking around after a shower. The bathroom was pretty grungy in general. It was miserably hot, but so was all Lyon while I was there, so not much to be done about that. The host did provide a fan.
When I arrived, the host was not home. His roommate let me in, and helped me connect to the WiFi. It turned out, the "WiFi" was just tethering to his phone, and this did not last once he left or his phone went idle. This was a huge problem for me, as I did not have an international phone plan, and was relying greatly on having access to WiFi in the apartment to coordinate with friends I was meeting up with.
Early in the morning on the day I was supposed to leave, someone started banging on the door and yelling aggressively. I was stunned (and don't understand French), and didn't know what to make of it. No one else answered the door, so I figured I must be alone. I was groggy and scared and not sure what to do, but I cracked the door open to see what the man wanted. He pushed his way in and proceeded to get up into my face and yell threateningly. I honestly was afraid for my safety and almost ran out of the apartment. He threw his backpack against wall and knocked some stuff off the shelf. I kept saying "No parlez vous francais," but that didn't seem to stop him from taking all his anger out on me.
Eventually the roommate of the host came out of his room, and said some things to the man. Apparently he was supposed to be a guest here, and didn't have a key to get in. The host wasn't home, so we didn't know what to do about him. He finally went into another room and slammed the door. I asked the roommate if I could reconnect to the internet, and then got messages that I had missed overnight while not being connected. Apparently the host had messaged me earlier asking if I could put my key back for the other guest. This is odd, as I was supposed to have my own key for the whole time. Furthermore, I was obviously not able to see the message since I didn't have internet. But at least then I knew what the man was yelling about.
The host never apologized about the incident, and if anything he seemed to blame me for not putting my key out for the other visitor. The fact that the man went ballistic is not the host's fault, although his negligence contributed to the unsafe environment and bad experience. Also, if you say you have wifi, temporarily having someone tether to a cell phone is NOT sufficient.
