We are a family of 2 adults and 2 teenagers and we stayed here for 8 days over the holidays 2018. The apartment was perfect for us. Nice rooms, well-stocked kitchen appliances and utensils (a bit more than the standard Ikea minimum ;-).
Also the towels and linens were nice. The owner was great and very responsive. When we had a little trouble with the wifi (which generally worked well) she responded and fixed it within a couple hours,
We will stay again when family again calls us to Vigo!
