The apartment is very good: safe, large, renewed and well located. It's managed by a third company that support guests. This company asked for my flight information, I provided it in advance and when I arrived at apartment one person was there to receive me and give all instructions (about keys, heating system, guidelines, etc).
It's provided towels, bed sheets to be used during visit. I would recommend you to take your shower soap and toilet paper (you can buy around)
There are a TV and sound system to be used, also a phone for local phone calls. In the kitchen some electronic devices are available for cooking and also laundry, if you need.
Heating system (2 heaters) were working fine, but smell of gas was a little bit uncomfortable (in the last day, just before leaving the apt one technician arrived there to check gas connections, but once I left the place I couldnt confirm if gas smells problem has been solved. I hope so).
In general, I would recommend this appartment, where you can have a very good staying,
