DO NOT STAY HERE, SECURITY ISSUE! When we arrived, everything seemed to be up to par; the location was safe and we accessed the building and our apartment with the codes provided without any issues. Our trip was supposed to be 4 days and 3 nights and unfortunately we had to leave a day early. On the 3rd day of our trip, we had a late morning and someone entered our room using the room code, not expecting us to be there. The person knocked first, but entered moments later, not allowing us enough time to reply. We quickly called out to the person from the bedroom once we heard the front door open and the person left the unit. My husband went to see what was going on, by the time my husband got to the hallway of the apartment and opened the front door, the gentleman was walking towards the elevator very quickly. When my husband called out to him and asked how he had our room code and if he was another guest, he said that he had just received an email with the code. He did not have items with him, as you would expect with someone checking into a room or maintenance staff. After contacting Vello, we were first met with excuses from the customer service representative that this was likely a maintenance staff but assured us that it wasn't another guest wo was mistakenly given the same room information. The property manager contacted us soon after the initial phone call and stopped by to change the apartment code within a half hour. The property manager appeared to be much more understanding and assured us he would look into the matter and let us know what he found. He also agreed to refund us for the additional day if we decided to leave. We left and checked into a hotel for our last day and night since we no longer felt safe. We received notification of the refund as soon as we confirmed with them that we had left the apartment, but when there was a technical glitch in accepting the refund, Vello customer service was no longer helpful and told us to contact Airbnb. My husband reached out to the property manager via text a few days later for a follow up, but we never heard back. As you can imagine, this definitely put a damper on our trip and left us with the feeling that this was an "inside job".
