It is a professional business, we thought we could get a cheap alternative instead a hotel.
When you rent the apt, you get a message with the hidden extras, you must pay the tax (2€ per person per day), a payment for overtime check in (after 19:00=25€, 23:00=50€)! At first we booked a transfer from the airport to the apt, on the day of flight the owner wrote me a message that he couldn't come. At least we had to wait for him in the night in front of the door (30min), he came to late and brought the wrong key for the apt. We went for a dinner in a street next door and he brought the right key after 30 min. For the mistake we had to pay 8€ less then the normal price. The location from the apt is very good, but the bed is not very comfortable, my girlfriend had a view days after it a very painful back after only two nights.
All in all we can't recommend the apt.
