The experience was great. Hong was waiting for me (even though I was a little late and without phone) and was really nice and helpful.
The apartment is small, but very confortable and has everything you need: good internet/wi-fi, confortable and clean bed, good size bathroom and good shower. It has a small kitchen with oven, refrigerator, micro wave and dishware (plates, glasses, pans, etc). Hong even provided shampoo, shower gel and a hair dryer =). Enough space for a couple. Location wise, it is also very good: 1 block from the metro.
The only con is that the apartment is located at the 6th floor without elevator, so you have to do a bit of an exercise, especially if you have heavy luggage. Other than this, it is great.
