The location was FANTASTIC, it really is super close to the Eiffel Tower and was in a pretty area - there were plenty of cafes and restaurants. The space was also very good and a really comfortable bed. The hosts were also really nice, accommodating and their English wasn't that bad!
The reason I have only given them a 3 is because of the communication around the check in time; the night before Patricia advised I would be able to check in at 2 PM which was later then I wanted but still manageable so I planned my trip around this. I caught a train from London and while still on that train and then subsequently not having any service on my phone she emailed saying she had made a mistake and that someone would be there until around 11 AM otherwise no one would be there until 6 PM. I of course didn't see this until close to 2 PM as I was in Paris for my first time exploring, but then had to lug my bags around for an extra 4 hours which meant I wasn't able to do a few things I wanted to do.
I turned up at the place at 6 PM (the instructions were confusing at first but they become pretty clear when you get there) it would be another hour before I would get in as they were stuff in traffic. This by itself wouldn't have bothered me so much but because I had already had my day thrown off because of having to carry my bag with me - it wasted even more of my time in Paris.
I probably wouldn't visit them again just because of the above however I also recognise that things happen that you just can't help; it probably wouldn't have been such a big deal if I had been there for a bit longer but because I was only there for 2 full days, most of my first day was wasted.
