Overall, really good price for value and location.
It says 4pm check-in, but that's only because there is a scheduled cleaning, which occurs any time between 11am and 4pm. We showed up between 1-2pm, and it was not cleaned yet; however, checking in went smoothly. We stepped out after arrival so that we wouldn't be there when the cleaning crew came around, and returned just before 5pm and it was cleaned.
The cleaning crew did a good job with cleaning the floor and surfaces. Although the listing says its a luxury studio, the only issue that clashes with that statement is when it comes to the bathroom. Its a very...very small bathroom, and the ceiling is also very low (i'm 5'6" and can touch the ceiling without fully extending my arm). The shower curtain did not appear to be cleaned, and if it was, it needs to be replaced. Also, maybe this was just because the people who stayed there last were very hairy people, but all of the drains in the bathroom were having a very hard time keeping up with draining the water.
However, we were not in the room much, so these issues were only there in the morning before sightseeing and when we came back later in the evening, so overall, the apartment was a comfortable stay for the price and location! The main living space is nice to be in, the bed was very comfortable, and the appliances looked/worked nicely. We did not use the oven or the microwave, but the dishwasher worked well and the fridge was nice and big.
I hope this helps for those having very specific questions that still needed to be answered! Also, in 3 days, we walked over 30 miles, so bring proper footwear, it may save your life haha.
