The service and communication from the ORM team was great and everyone was very helpful and friend - they even offered to keep our suitcases in their office until our afternoon flight :) the room had everything we needed and was in a fantastic location!
Although we had a good stay, and the apartment is in essence very quiet, if there are other guests staying in the apartment above you can hear their every move and conversations, and also random loud bangs. You can also hear everything from the main hall, so if you are a light sleeper you will want to take ear plugs to not get awaken by people coming in/going out. Hopefully carpets or rugs/mats could help alleviate this.
The toilet door has to be pushed hard to close it properly, which causes a really loud noise, so we had to keep it ajar most of the time to avoid this, especially if getting up to use it over night. However, I believe th ORM team were looking into fixing this after our stay.
