From what time can i arrive on the day of arrival?

For our mountain cottage, there is a general cottage check-in between 3 p.m. and 4.30 p.m. on the day of arrival. With our detailed directions you should find our rental without any problems. If you find out on the day of arrival that you cannot keep to the time window, please let us know by telephone around 2 p.m. However, if you plan your arrival accordingly in advance, it should be possible to keep to the time window without any problems. After 9 p.m. it is no longer possible to take over the rental. On the one hand we are private landlords and on the other hand we live 35 kilometers away from the cottage.
