"I'll start with the positives, Cala Millor itself is great. The beach has white sand and clear water, there are also an abundance of cafes, shops and restaurants in the resort.
The negatives relate to the hotel itself. The Blue Sea Cala Millor is very tired and in desperate need of refurbishment. Our party was split across three rooms in block two. The air conditioning in this block was barely functioning (the air conditioning is only in the rooms and not the common areas), and the system is very loud. Most nights we were woken up by the noise the air conditioning was making. In one of the rooms the air conditioning leaked water for the last three days, this was reported but no maintenance was carried out. As a result, various towels were used on the floor to catch the water.
The bathrooms across all three rooms were not great. One room had a broken toilet seat, tiles were coming off the walls in all three bathrooms and ventilation is non-existent. The smell in one of the bathrooms was pungent at check-in and barely improved over the course of the week. It was also somewhat hit and miss as to whether the toilets would flush, the mechanisms are loose had to be fiddled with on occasion.
The standard of cleaning in the rooms was not great, some of the plug sockets were broken or had loose fittings, and the TVs did not work. Particularly worrying was how wobbly the fittings on the balconies were, not sure how these can pass a health and safety assessment.
The lift in block two broke down three times in the space of five days, on one of these occasions two of our party were in the lift when it stopped working. Luckily they had a mobile phone on them to inform the rest of us as the emergency button did not connect anywhere or to anyone. Reception only became aware people were trapped when we told them, not that they were particularly interested. Even when questioned about the emergency button not connecting anywhere, the reception staff were not bothered.
We also had the pleasure of the fire alarm going off twice during our stay, one of these was in the early hours. When we asked why the fire alarm had gone off it was blamed on the "humidity".
The pool areas were clean enough, although only one of the pools has a bar. When using the second pool you had to walk across the road to get drinks. Whilst the pool bar had pastries on offer for guests, these were in an open container which was often frequented by wasps. The wasps were also frequent flyers around the spirit bottles and drinks dispensers at the pool bar. The music being played from the pool bar, which was loud enough to be heard across the road at the second pool, often included songs with profanity in the lyrics which isn't exactly appropriate for an environment that has children around.
A number of the sunbeds around the pools were broken, but were still laid out for guests to use. One such sunbed broke when one of our party sat on it, this was put to one side where it remained for the rest of our stay, rather than be removed. Of the sunbeds that were not damaged, all were uncomfortable and could be sat or laid on for any length of time.
The food provided in the restaurant did not offer much variety, and does not have enough tables to cater for the number of guests staying at the hotel. A common site was guests clearing tables so that they could be the next users of that table. The snacks on offer during the afternoon are in the restaurant (rather than being available at a pool bar) and usually consists of leftovers from lunch alongside anaemic looking burgers.
Overall, Cala Millor is a good resort but the Blue Sea Cala Millor is not the hotel to be staying at."
