I enjoyed my stay at Pia & Jean-Pierre's place. I decided on it because of the balcony feature and am glad I did, as I enjoyed my tea in the morning and glass of wine in the evening. I was skeptical because it was not centrally located, but there is a good transit center within blocks for the bus and Metro which I used daily. The neighborhood and building felt safe even as I walked alone after dark.
The bed was very comfortable, the kitchen small but adequate enough to do light meal prep, the shower hot with great water pressure, and I enjoyed the tub one evening.
As I had had recent hip surgery, the elevator was greatly appreciated. Just an FYI, the light in the hallway from the elevator to the unit isn't motion sensored so you have to push one of the illuminated switches on the wall...but be careful not to ring someone's doorbell which I almost did. And though the unit does not smell smoky, the hallway has a heavy sent of old smoke in case that might cause any respiratory problems.
Probably the most important thing to say is how communicative and available they were when I had questions. Enjoy your stay!
