Check in was hectic. I waited one hour at the lobby of the building and could not get any assistance. I even had to go to the pizza shop next to the building to borrow their phone to make a call to sweet Inn (they provided a number for me to contact) but every time I call through, it asks me to leave a message and I was unable to speak to a person.
Communication wise, it seems that they have a team of people handling various people so you don't always speak to the same person. Which also means you will have to repeat your situation a few times to get your point across. One of the team members even mistaken that I was checking in the day after when I was already there.
The shower was not great. The drain clogs up very quickly so you will be standing in a puddle of your shower water while showering.
The apartment window opens up to a road with trams so it is rather noisy and you can hear the trams start as early as 7/8am.
