Our stay at the Helena and Artur's apartment was fine. Lots of space, plenty of natural light, and we enjoyed having the balconies to lounge on (great view). The issue that unfortunately marked our stay came about when we checked out of the apartment. When we checked in, an employee of Helena's and Artur's told us that, when we left the apartment at the end of our stay, we were to leave the keys in the apartment, close the door behind us, and exit the building. This we did, but the door to exit the building was locked from the inside. A key was required to open it, but we had just left the keys inside the locked apartment behind us. We were stuck in the stairwell at 7am, with a taxi waiting for us outside to take us to the airport. This was the first time that a key was required to unlock the street door from the inside. We were in a serious hurry to return home for a family emergency. Being trapped inside the building was unsafe and quite claustrophobic. I called the number for our host, and I spoke to a man I believe was Artur. I calmly explained our predicament and told him which address we were at (it seems he manages multiple properties). I asked him to please come as soon as possible let us out of the building. Instead of coming to the building, Artur proceeded to argue with me about our situation. He insisted that there was a button on the door that would undo the lock. Standing in front of the door myself, I explained to him that there was no such button. He insisted over and over again that there was, completely ignoring my responses that there was no button and that we needed someone to come unlock the door for us. After 5 minutes of this calm yet pointless back-and-forth, I became quite vocal about my frustration. Artur asked which address we were at, and when I told him--again--where we were, he became quite embarrassed and apologized for insisting there was a button to unlock the door when there obviously was not one. Artur then explained to me that he was 80km outside the city and had no way of getting back to let us out. He told us he would phone an employee who would come over right away. He then called me back a few minutes later to say they were on their way and would be there soon. After 20 minutes, I phone Artur to ask how much longer we had to wait. My mother was distressed and very anxious to leave the building. He told me it would be another 15 minutes. When I asked if it could be any sooner, he hung up on me. It wasn't until 7:50am that a woman finally arrived to release us from the building. We jumped in a taxi, rushed to the airport, and fortunately made it just...
