Paula's place was very convenient, within close proximity to the train station. It was a bit of a walk the first day considering we had to haul around our luggages and figuring out the metro and how to get to the apartment. We were waiting outside for a while because I didn't know you needed a key to get in. I messaged Paule and good thing she replied back within 5 minutes and told me I had to ask for the front desk through the intercom. I was a little afraid since I didn't speak any French. I asked anyways and I don't think the receptionist understood but she still opened the door for me. We were then faced with doors on both sides and again we needed a magnetic key. Good thing a guy was coming in and he used his key to open the door for us and even showed us where the receptionist was. That was pretty much our biggest hick up of our Paris trip. We also tried using the pool, but we could not find it despite the instructions Paule gave us. The room was pitch dark so we walked away a little disappointed :(
A little tip to future travelers in the summer, there is no AC, but there is a fan available and you can open the windows if you don't mind. I noticed having air conditioning is very rare in Paris. Some high end stores don't even have AC which is really odd.
Overall, we had a wonderful stay due to the convenience of this studio and it made our trip a lot easier.
