The apartment was great. What I value most is the parking space (just next to the entrance btw so if you have heavy luggage you will be just fine) and the easy check-in. We arrived close to 23h due to enormous line on the border, but Maria was replying to the messages very quickly and the check-in was fast and thoughtful.
The location is also good, it is not noisy, it's 30min walk from the White Tower and via cab we paid 3.60 euro, although the cab driver maybe didn't include initial fare of 3 euro (another passenger was just leaving the taxi when we stopped it), not sure. You can go the center with your own car if you prefer (if you are an experienced driver), but walking is also fine, at least on your way in or out.
The apartment had everything needed, even some things you don't find in other places, like a medical kit, coffee etc.
Overall we were very happy with the apartment and we will visit it for sure in our next trip to the city.
