The owner's friend met us and was very very nice. She walked us through everything in the apartment and how it works. She's very responsive - we came back in the evening one night to find the apartment with no lights and she responded within minutes to help us handle the issue. The only downside is no AC, so keep this in mind if traveling in the middle of the summer!
The apartment is very cozy, perfect for 1 or 2 people. The bed is surprisingly comfortable, and the balcony is great. It's an amazing location, very central and close to both public transportation and taxis. It's also really nice that you can see the tour Eiffel light up at night. Overall, we were very satisfied and would definitely go back!
