We stayed 10 days with our family (4 adults, 4 children, and 1 teenager). The check-in process went troubleless. We had very good communication with Ju & Ch. The 4 flights of stairs were not a big deal since we did not have a lot of luggage, and the stair are large. There are 2 bedrooms on the main floor with comfortable space. One of them is separated from the kitchen/living by some glass windows. So it is noisy if someone is using the kitchen/living room. The other 2 rooms are upstairs. They are spacious but with low ceilings at some points. it has 2 full bathrooms. One of them, the bigger one, has a good shower with warm water and a toilet with a very close wall in front of it. (we used it seating by the side). The other bathroom has a bathtub with a shower. This shower doesn't get too high. I would say the tallest one capable to use it must be around 1,75m. The water in the shower doesn't get too warm (you can get very warm water in the bathtub if you fill it slowly). The apartment is located a few steps from metro station and bus stop. It is very easy and quick to get to the main tourist attractions. The apartment doesn't have a washing machine, we used the closest laundry store which is just around the corner. Just be aware that there is a brothel in front of it. We did not have any problems with the neighborhood. Nevertheless, the people in the apartment´s street didn't look too friendly, especially at night. One night, there was a prostitute working on the street of the apartment.
