The apartment was very nice and clean The WiFi reception was great. I was in apartment 3 and there were 65 steps you had to climb to get to the apartment. Inside the apartment the bedroom and bathroom were up another 15 steps. I personally was bothered by walking up the steps. I am 67 and I have friends my age who would have difficulty climbing up and lugging suitcases up these stairs.
Also, you are in a great location steps away from the Grand Palace with many bars and restaurants near by and you are very close to the train station. But it gets very noisy in the evening and early in the morning. This is the same in any apartment in the area. It is not unique to this apartment.
For me the location and niceness of the apartment offsets the steps and noise.
I would stay here again.
