We stayed three nights at The Yen Homestay and it was great! Its a little bit out of the busy center so you can enjoy the (quietness of the) nature which we really liked. The view from the balcony is beautiful: you see the ricefields, the river and huge mountains. The house has a cool atmosphere, its different from other homestays, this place feels more 'real'. The family really did their best to make us feel welcome and the food was delicious! I can't think of anything that should be different and if I come back to Sapa, I will stay here again!
