We really enjoyed our stay at Daniel's apartment in Ciutadella. It was perfectly presented and decently equipped.
We were travelling with our 6 month old baby and Daniel went above and beyond, arranging for a travel cot and high chair for the duration of our stay. He also offered to get us items from the supermarket before our arrival as it was almost 10:30pm when we actually checked in.
The one negative aspect of our stay was the apartment's location. It is very close to the centre of Ciutadella as described - it is also opposite a large social housing development (as mentioned in the description) which didn't bother us. However, the apartment is on the ground floor of the building and facing onto the street. There was a lot of vehicle noise day and night which was at times irritating and at other times made it difficult with trying to get the baby to sleep. Additionally the apartment was adjacent to the main building door which slammed loudly every time someone entered or exited, day and night.
On our last day we had a late flight home and Daniel very kindly let us stay in the apartment as long as we needed and well after the usual check out time. This was ideal with the baby and much appreciated.
