Hi I am the host of Happy homestay at Hanoi (Tay Ho) and Lovely house for rent at Tay Ho.
This is a nice place to stay. I have stay here before and the host is very friendly. They willing to recommend many different places in Hanoi for you to visit (included good places for sight-seeing, good places to eat, good places to hang out, ex.)
The house look exactly like the pictures. It's bright, clean, modern in the nice and safe neighborhood where there is a lot of foreigner around.
I definitely recommend this place to anyone want to visit Hanoi in short or long period of time.
