We stayed in Laurent Et Audreys place for 4 nights end November/beginning December. It was perfect for 3 of us (2 adults, one child). It is small but everything you could possible need for a few days stay is there. It was spotlessly clean and tidy with a well equipped kitchen and a fabulous shower.
Check in was seamless, we arrived later than we had expected but this was not a problem. We only needed to communicate with the hosts on arrival and when checking out and they responded to us immediately in a lovely polite and helpful manner.
Location wise this was an amazing place to stay ! There was a metro station literally 2 minutes from the apartment. There are also bus stops nearby but we didn't take the bus so can't comment on reliability etc. We got everywhere we needed to go in Paris using the metro. There is a fantastic supermarket right next door and there are loads of restaurants around. It is a lovely area, lively but quiet enough at night.
Overall I would HIGHLY recommend this place. Communication great, location great, facilities great. Would absolutely book again if we are lucky enough to get back to Paris soon :)
