From mixed comments which I have read about Don Salva over the years, I think that satisfaction and overall holiday enjoyment at this complex very much depends on the age of the guests and at what time of year they are visiting.
During the peak summer months for example, groups of 18-25 year olds may well find acceptable what couples with young kids may not. Everyone has different standards, expectations, requirements and priorities and while some may only be looking for somewhere to kip after a late night on the town, others may be expecting a good standard of accommodation and facilities in comfortable and quiet surroundings. Inevitably, some will be delighted while others may be less pleased.
One thing which doesn't change about Don Salva all year round, is that it is situated next to one of the busiest and noisiest road junctions in Benidorm.
