This is an excellent location with really nice apartments! There is so much within walking distance and its right next to the main train station. Plus they were prompt to help when we made requests. However, we did have a couple issues that prevent me from giving a full 5 stars.
First, the self check-in is great! But is behind a locked door... They should provide customers with a code to get through the door. Our phones couldn't make calls. We got lucky that someone already staying there was coming back and let us in.
Second, our room was SO hot (when it wasn't hot outside!) and the AC in our room didn't work. We asked them to fix it but they said they would send someone and didn't. Unfortunately, the building is right next to the tram line and many bars so it was always too noisy to leave the windows open at night.
Third, the location is very noisy. Bring ear plugs.
And fourth, the airline lost our stroller and had it dropped off the next day, but because there is no front desk and no way for anyone to get past the first door without a code/key, the delivery guy couldn't get a hold of us. We're lucky he waited for an hour until we happened to come out!
