I had a very comfortable stay at Huyen's flat! It had central heating, and it was very modern, with wonderful balcony space. It was also in a modern and safe area close to supermarkets, which was a bonus. It is about 30 minutes to walk to the central station, and about 15 minutes by bus. So maybe it is not the most central place, but very accessible. Huyen and Robin were very responsive to my questions, helping me check-in and check-out with ease.
