I can absolutely recommend to stay at Yen’s! I stood here for 6 weeks and therefore I can tell that she is a very nice host and answers very quickly. Check in and Check out worked perfectly, she is very accomodating!
If you stay here in winter just make sure to bring warm clothes. There’s an AC in the room which keeps it cozy but the common rooms are >not< heated! So be prepared ;).
Furthermore the location of the house is really good. You can directly go to the City Center by bus, the stop is literally in front of the house.
I had a really good time here!
