I spent 2 weeks volunteering at Casa Hogar Torre Fuerte in October 2017 and my only regret is that I couldn't stay longer! The staff at Volunteers Peru (Marita, Megan, and Sarah) are truly amazing women and it was such a joy to get to know them. They are kind, friendly, and very knowledgeable about Peruvian culture. If you have any questions before or during your trip, don't hesitate to ask them!
As a first-time solo female traveler, I was a little nervous about safety, but I felt completely safe in Arequipa and especially staying at Honey House.
I would recommend learning as much Spanish as you can before you go, but don't let your lack of Spanish prevent you from going. I do not speak Spanish but I was still able to play with the girls and make bracelets with them.
Casa Hogar is less organized than a lot of programs in the United States, so staying flexible is key. Volunteers Peru has some supplies (craft items, coloring books, etc.) that you can bring to the house, but if you want to do something specific you will need to bring the supplies.
Overall I would highly recommend this program. You have mornings and weekends free to explore Arequipa, and what better way to spend your weekday afternoons than impacting girls' lives? Not only will they be blessed by you, but you will be touched by them. Exploring the world and immersing yourself in other cultures will change, shape, and grow you. Do it!
