Wrong address for the apartments.
The hospitality was great, Sandra and the staff were really friendly and helpful.
The only problem is that the apartment is not located in Ciutadella as wrote in the description but it is located in Los Delfines which is 15 minutes by bus from Ciutadella.
Another issue we got was that we had to pay the city tax once we arrived. Nothing expensive but it is not mentioned in the ad either.
A part from that, everything was great!
