Depending on what kind of trip you aim for this place is hit or miss.
If you are planning to just leave your stuff here, sleep and take shower, then this option is very good (basically spend most of the time being tourist) - you get bang for the buck . Otherwise look for another place.
You will be sharing the house with other people (so if your timing is bad, then you will need to wait for your turn to get to the bathroom). Good thing is that they are quite quiet, sadly walls are a bit more on thin side. So if you are person who wakes up easily, it could be a problem.
Place was very clean and provided with all basic stuff.
Airport is indeed around 15min away with taxi. You can get to the center with 2 hops with a busses.
I am not sure if I wasnt smart enough to find out how to open window or it couldnt be opened in the first place, but result was still the same. Air could become stuffy after a while.
