Irene's place is an absolutely fantastic location. We were two female travelers and we felt very safe the entire time. The street could be a bit loud at night, but nothing unreasonable for such a big city. It's close to two very reliable Metro lines (the 7 and 10) and within reasonable walking distance from both St. Germain and Notre Dame. Many other reviewers have commented about the size of the space and it is certainly VERY small. If you are tidy and willing to go without absolutely any privacy you will enjoy the really nice space. Although we thoroughly enjoyed the charming place, there were, in our opinions, some issues with cleanliness. The host generously allowed us to check in early and I think there may have been a miscommunication about cleaning later in the day. However, I do not think the place is ever really thoroughly cleaned. You could feel the dirt on the floor, there was old food in the fridge, and trash remaining when we thought the place had been cleaned in our absence. The biggest issue is that while searching for a lost earring we found a used condom under the mattress. To me, that is a sign that the sheets are not being regularly changed. I would have loved to come to a sparkly clean place for the price we paid, but we were certainly able to cope. Overall, we had a really lovely stay. Hopefully, the cleanliness will improve for future guests.
