I would definitely recommend Maria's place for single female travelers. Maria went out of her way to ensure that I was OK while I was out travelling in Paris. I had access to her place at all times.So I could go and come as I pleased. She stays very close to the Arc de Triomphe and Champs Elysee's as well as the the Metro. She was very efficient in responding to my messages. I loved the little details in the room for e.g. the Bottle water, biscuits, yogurt, kettle, TV etc. She even put the heater on to warm up my room before my arrival because it was very cold the day I arrived. I arrived at 10 pm in the evening and she waited up for me which was so kind of her.
