Hi. You can easily get Sa Pa with a public bus from the Lao Cai station (about 1 hour), and then from Sa Pa centre a taxi to the homestay(30/40 mins).

You are more than welcome. When you leave I would suggest go via the cable car up mount Fransipan! It’s bloody amazing! It costs 700.000 to be on top of the world and looking into China. One other recommendation is to maybe miss the night bus. We did this direct to Cat Ba from Sapa after the cable car. The bus didn’t feel exactly safe and was very long and uncomfortable. Instead go back to Hanoi and better to get train. Be aware of using the best train companies for overnight as they have rules. One detailed two days ago and often the cheaper ones go to fast. Cat Ba! Overrated and didn’t like it! Of you can afford it and want to see H Bay take a sea plane from Hanoi, look from the sky! It lands on the water. You can then swim and eat and return back to Hanoi and then get the train to the next place. I don’t recommend train/bus to Cat Ba or H Bay and then staying there and certainly don’t recommend the boats which blast out terrible music. The sea plane will stop for two hours while you eat and swim which is enough to see the place Any other questions let me know.
