A nice apartment in the center of it all. Fourth floor walk up in an older building on one of the busiest streets in Paris. You walk in and it just feels so Paris. When I was there there was some construction going on outside and in some of the apartments that was creating considerable dust but this is to expected in a major city. Two things to consider when staying here:
1.) The apartment is on a very busy street, with people eating outside most nights well into the night (2AM and later). With the windows closed it's not too much of an issue, if you're not too bothered by noise. But be aware of that if noise does bother you.
2.) The main bedroom doesn't have any windows. And it can get rather stuffy if you don't keep the door open. In the summer, when I stayed, the room can get very hot. You can leave the door to the bedroom open and open up the windows in the living room, but then the noise from the street can be very loud, particularly on Thursday, Friday, and Saturday. A fan would have been nice.
The place is well equipped. The internet works well. The sheets and towels are extremely commerical (very coarse, even harsh on your skin) and you'll need to bring all your own toiletries. It has all the quirks of an older French apartment.
Read the contract they offer carefully. They have some silly policies you should be aware of (they charge you 150 Euro to check out on a weekend). And I definitely felt nickle and dimed by them (I left the aparatment extremely clean, they found two little pieces of paper on the ground and charged me an 80Euro cleaning fee; they charged me 27Euro to wash the sheets. What was I supposed to do? Not have sheets on my bed the last night? Also, I did leave a second pair of completely clean and ironed sheets in the apartment for them, as requested by their contract). In short, this was a silly and cheap way to extract more from me and it left a very bad feeling on my part. I paid over 7000 for this place and their charging 28 Euro to clean the sheets and 80 Euro to clean the apartment even though all they could point to was one small piece of paper on the floor was, quite frankly, ridiculous. Overall the extra fees were 140. I complained and they reduced them to 80. But this was clearly a strategy to squeeze more out of me and I didn't appreciate it at all.
It's not the best apartment I've stayed in but it's probably better than average in Paris. And if noise doesn't bother you much and you want to be near everything (including amazing public transport), this is a good place to stay.
