Planning to visit Paris, France Oct. 2-5. Can someone suggest good hotel ( not very expensive and friendly)?

By kirlakIn Paris those don't exist.
In paris..??non x-pensive..???yeah i know..streets!!!hahahah
Inexpensive can be done if you stay outside the city, or down scale your expectations.
Friendly, you will not find this quality in the Parisian hotel industry unless you spend lots of money and are not from the America.
Check out Hotel Montebello. I stayed there two years ago. It's near a metro stop and les Invalides. It cost 44 Euro per night for a double (if I am remembering correctly.) It was nothing special...but it had a bed and our own bathroom. I only saw one worker; he was nice.

I found this hotel through Let's Go Europe. I hope this helps!
Most of the cheap hotels in Paris are imposible to find online. You have the roam the district you want to stay in and find one or stay in an overpliced chain. I found one off the commerce metro stop for 32 euros a night.
Hotel Bonséjour, rue Burq, 75018 Paris.

Situated in the charming district of Montmartre, the Bonséjour is unpretentious, with clean comfy rooms, some with little half-balconies. It cost about 45 euros a night for a double last time i was there; not the cheapest in town, but a good quality/price ratio. It is a couple of minutes walk from Abesses or Pigalle metro and a short walk from the funicular tram up to the church of Montmartre.

Stayed twice and would definitely go back.

For a memorable and reasonably priced meal, it is worth visiting Chartier (metro Grands Boulevards). The interior is virtually unchanged from the 1880s original and the prices, considering the decor and location, are reasonable.
Hotel Andre Latin,
42 Rue Gay Lussac.
Hotels are quite expensive but depends also of what you want to do during your stay..a good location cost more more but you will save on taxi and metro tickets. it is also more conveniant to be in centre...
you can also book a room"chez l'habitant"...
