The aprtment's location was ok. It was in a shopping street and it took about 10 minutes to walk to the Cathedral. But when we arrived, it was very quiet and we could hardly find a restauruant open.
In addition, we had a problem about the price of the reservation. The host originally listed the price for 40€/night. When I made the reservation, he raised it to 50€/night per 2 persons (he sent me a "special offer" for the price). Then after our communication and agreement for me booking it for 3 persons (additional 1 person), he sent me another "special offer" and raised it again to 50€/night per person, while clearly knowing I would book it for three persons. I did not notice the change and accepted the "speical offer." So I asked for the help from airbnb's customer service. The host told the assistant that he usually lowers the price when there is no reservation and he even wanted to raise the price to 70€/night at first. We are talking about the price for the same day of the same week. To my suprise, airbnb's custermer service assistant replied to me saying that it is ok for the host to raise prices as he wants AFTER I have confirmed the reservation. We were fine with paying the extra cost of the additional person after 2 guests. But we thought it was unacceptable and unreasonable for the host to raise price as he wanted and changed the price for only 1 person (requiring us to paying for additional 2 guests), irresponding to the information of his list. However, on the day before our arrival, he sent a message saying we had to accept the "offer" to check-in. We ended up paying much more than the originally listed price.
Another small issue is that the host agreed about our late check-in before we made the reservation. However, on the day of arrival, he insisted we must take a taxi from the airport to the apartment which incurred an extra cost for us. It was ok for us, but I just felt that the communication could have been more of considerations from guests' perspective.
All in all, we suggest others to be very careful when you make the reservation and accept the "special offer." We thought it was not reasonable for a host to list a lower price to attract the attention and later raise the price without clearly informing his guests.
