Sejal, busca una niñera - 08001 Barcelona

I just moved to Barcelona a month ago with our 3 children (from 13, 11 and 5 years old); We live in La Salut in Gràcia. I need to travel for work from Sunday, October 8 to Monday, October 16. I will take my 13-year-old daughter, but I would need childcare (someone who comes to stay in our apartment) for the 2 boys. I will also need the same but for all 3 children from Sunday, October 22 to Monday, October 30, when I travel for work again.
During the day, the youngest one who is 5 years old attends a school that is an 8-minute walk from our apartment. The older two children attend an American Online School and do their work from home. They are able to stay by themselves.
Basically, we need someone to be with the children from Monday to Friday from 3:30 p.m. to 10:00 the next morning. From 10:00 a.m. to 3:30 p.m., nothing is required on those days and you are free to do as you wish. During the weekend, care would be needed all the time unless my daughter will be there to watch her brothers for a few hours.
We also have 2 very sweet Labrador dogs.
Payment would be €500 for each of the 2 weeks and we will also cover the food for you during that week as well. You would have your own room in our apartment. Thank you!
