We agreed upfront with Homm that we would arrive at 1 AM and that we would use the key box to enter the apartment. However, upon arrival there were no keys in the key box. They were not reachable in any way (Airbnb message, general Homm customer service, no possibility to call a phone number directly). We gave up eventually and had to find a hostel/hotel at 2 AM, which is quite difficult to do as you can imagine. We were able to reach Homm around 10 AM in the morning. Instead of apologizing and helping immediately their first response was if we ‘had found the key box’… Further communication remained slow and passive and they gave no explanation of why the keys weren’t there. No timeline of when it would be solved and even an apology seemed difficult.
Upon entering the apartment we discovered the warm water did not work. There were no instructions in the apartment (as stated in the message after the booking confirmation) of the water system. We had to message them again. We repeatedly had to ask them what the next steps were. We suggest Homm in the future to immediately send the full instructions and an estimation of when it would be solved.
The above two experiences resulted in our conclusion of their bad customer service.

On a positive note, the apartment itself is great. It is similar as the pictures, it is clean and new with well working appliances. Bonus points for the effective and quiet air-conditioning, as well for the blinds that darken the room instantly. AC and blinds are available in the bedroom and living area. The apartment building felt safe, as well as the whole neighborhood of Thassio. Thassio has limited cars and people with only a few places for drinks/food. This leads to a quiet and safe environment to sleep in. There is a well-stocked large supermarket, pharmacy and bakery around the corner.
