I had a great stay at Rainer's place ! Both Rainer and his fiancé Iza were very hospitable and friendly, always up for a good chat and more than happy to provide you with any tips/recommendations. I also enjoyed getting to know the others staying with Rainer, everyone was very polite and his home was immaculate.
However, a lot of privacy is given as well, which was great. The room was clean and comfortable and exactly as depicted by the uploaded photos.
The location of the apartment is extremely convenient with an mrt station within walking distance (3-4 mins). There are are also shops and supermarkets in the vicinity. Lots of local foods in the area as well (you won't ever starve !)
