I really had a great time staying a few days with Dorothy. The place is super clean, really well situated and very quiet. You can even see Taipei 101 from the living room !
Dorothy is really discreet and let you enjoyed the apartment like it was yours.
As she speak perfect English, you can exchange on many subjects with her, which make your stay even more enjoyable.
For people with limited budget that are also looking for meeting locals, this is a place I recommend without any hesitation.
