Armand's parents were lovely to stay with, friendly and made me feel welcome from the start. They even bought me croissants every morning for breakfast!
The house was very clean and matched the description well. There was central heating so when i felt cold, i could turn it on and it was fast at warming the place up.
Right next to my bedroom was the bathroom and shower and kitchen, everything was easy to access.
Its a fairly central location in Paris and i walked to everything i needed although there are lots of public transport options around the place.
The apartment is on level 6 and while there is a lift, you do need to go up half a flight of steps with your luggage to get to the lift, and another half to get to their unit. But given its Paris, i did not mind, most places don't have lifts. The lift is also tiny, enough for one person at a time i'd say, but once again thats normal for europe in my experience.

William (Armands dad) spoke great english and explained everything to me as soon as i arrived. His mum didn't speak english but we got on fine, i could pick up what she was saying and when necessary, i used Google Translate in my iphone, which was a massive help to both of us when William was away for a few days. His mum was impressed, i don't think she new apps exist to help translate this well. I recommend everyone downloads Google Translate app, regardless of where you stay, its very useful!
