Looking for quite and clean apartment near Rüsselsheim area (max 50 km)

Hi,

My name is Baldomero and I am 33. I am Part-time Proffessor and Researcher in Spain (Universidad Miguel Hernández de Elche). I am visiting Hyundai Motor Europe Tech. Center for 6 months starting in June. I speak English and Spanish, but I don't speak German even though I am looking forward to learn. I am looking for a private bedroom in a clean and quiet apartment near Rüsselsheim area (max 50 km) -It would also work for me a single bedroom apartment. Since I will be there for 6 months I do prefer if the appartment is already furnished. I like to cook so I want to use the kitchen. Laundary at home makes things also much easier. I will go to Germany by car so its preferably for me if there is free parking near the property.
I have been a couple of times abroad (USA, Italy) so I am used to live with other people, so far it has been a really good experience with housemates.
I don't smoke but I don't care whether other smoke at home or not as long as the smell is not too strong.

Please do not hesitate to contact me if you have further questions.
Regards
Baldomero
