Visited Hanoi after 2 year hiatus.
In my previous experience, it’s harder to find action in Hanoi compared to Ho Chi Minh (Saigon).
This time round, I had a local friend to bring me around.

Typical massage parlors in Vietnam will only offer massage + Handjob.

My local friend brought me to Geisha Sauna & Massage where they offer massage + Blowjob + Handjob + 30mins in common pool with a bikini girl.

This place will be hard for foreigners unless you bring along a local since the reception and girls can’t speak English.

You start by putting your personal belongings and clothes into a locker.
Then you move to the common sauna and pool area.
After 10 mins in the common pool, your girls wearing bikini (you can’t choose your girls), will then accompany you in the pool.
In the common pool, you can have some mild foreplay for 20-30 mins.
Once you are done in the pool, the girl will bring you to rather public shower area (no doors) and will clean and shower you. No hanky-panky during shower, but the girls will clean and wash you pretty thorough.

Once shower is complete, you will be brought back to your locker area to collect your personal belongings and the girl will carry them back to your private massage room.

In the private massage room, the girl start by giving a 10-15 proper massage before she partially undress (up to her waist) to give you a boob massage.
She’ll then proceed to give you a BBBJ and also a HJ.
Throughout the session, you can caress and molest the girl freely. The girl will be very a very loose clothing that’s meant for you to roam, caress and molest her.

For those that prefer some privacy, there's an option for private bathroom instead of the common pool but according to the locals it's more fun in the common pool since you can check out your "neighbours" bikini girls.
