We didn't meet Angel, however a lady from a company was in charge.
When we left the airport we called the number provided as we were told, when we arrived she wasn't there yet so we called again and she would be there in 10-15 min., however it took her over 35 min. to finally arrive. She quickly showed us the flat, she didn't seem very welcoming. Anyway, the flat itself is very nice, it was clean and nicely decorated with a great rooftop terrace. The items provided are very very basic, the rest you need to buy yourself. Two curtains were broken when we got there, luckily they got fixed the same day. Upon departure the lady came to pick up the keys and was already standing in the door with the next guests, this was a bit awkward. We didn't leave for the airport until the evening, so we stored the luggage (and had to pay 10EUR) in the basement.
