The location and the property in general were good.
We were also able to leave our luggage by the entrance upon checking out, which was ( relatively ) safe.
Cleanliness was very bad- especially the toilet hasn’t been cleaned. This is unacceptable.
Wardrobes were a bit messy with probably used blankets.
There was only one big towel for each guest. It would be good to have at least one more for each guest.
Communication wasn’t very well, especially upon check-in and there was no warm welcome or any kind of connection between the employee and the guests.
There was no wifi, however, the company had informed us about this the previous day. Unfortunately, the problem was still unresolved when we arrived and as a result there was no wifi at all- but I understand that technical issues do occur occasionally.

If the above are improved, the flat would be recommended.
