Extremely loud
Not clean
Inflexible host with a rude communication style
I had a horrible experience. The apartment has terrible noise insulation so it's impossible to sleep. Since it's located in front of a very busy boulevard, you will hear cars, people, karaoke, all day long. So unless you're a heavy sleeper this is not the place for you.
The building, I imagine was affected by the earthquake a few years ago, so the apartment is not straight, there's a slight slope which is weird. In bed you'll feel like you're head is lower than your feet, for example.
Lastly, I was very disappointed with the communication with Remedios. I'm not sure if it was automated response because it felt so. For example, to my question "could I have an early check in?", the answer was "Check in times are blah blah" , with no consideration to my question and zero politeness. Furthermore, half an hour before my check out, Remedios contacted me to ask about check out and I told her I was on my way back to the apartment to what she responded that there was a fine for late check out.
I absolutely DO NOT recommend.
