I had a wonderful week. if someone is really looking to get started actively to lose some weight in a short period of time, then the 7-day program at El Palasiet is highly recommended. Not only have I lost 2 kilos in 5 days, I have also been greatly stimulated to pick up a healthy lifestyle again. In addition, of course, a hotel with great facilities, friendly and very thoughtful staff, for example I was given a delicious lunch on the day of departure. A few points of attention for everyone who goes, it was no problem for me, but good to pass on to those who go there. People are not equally good at English everywhere but if you just let them know that you don't speak Spanish then you will be well supported. The program is quite full, so take a good look at what really suits you and what you like. Go for a walk just by yourself for an hour every morning, even if there is no walking session, it´s beautiful! Thank you so much for arranging the trip, I enjoyed it!
M., Netherlands - 14 June 2022
The organisation by SIS was very good, everything was correct and easy. My first impression on arriving at El Palasiet was that it was a peaceful place, where I could really disconnect and enjoy a few days to myself. The place was elegant (some parts of the hotel were a bit old, but charming and unpretentious), the rooms were spacious and with spectacular views, everything was very clean, the staff was very friendly and the clinic, which has been recently renovated, was beautiful and able to transmit peace. Achieving goals on a physical, psychological and emotional level, as well as allowing you to change routines and incorporate healthier habits in a progressive and natural way. I believe that all of this is achieved at the Palasiet. Obviously, one week is not enough time, it would be better to spend at least two weeks (ideally even more...) but in just one week you can lay the foundations for a healthy weight loss. I would have liked to have a bit more free time. The programme is very intensive, which is good, but I would have liked to have had more time to read a book in peace and quiet, and to go for a few more walks on my own. Apart from the professionalism of the whole team and the feeling of having paid for something that is really worthwhile, I take home with me the fact that I have brought a general awareness of wellbeing, of doing something 100% for myself, which also has a transcendence beyond the days I was there, as it has allowed me to "change" the chip and refocus my eating habits, physical activity and self-care. As a final comment I have to say that I have been very satisfied with this programme. This type of experience is not cheap, but when you see that what you pay for corresponds to the service you receive, you pay for it with great pleasure and are happy to be doing something good for yourself. I met people of different economic capacities in the hotel and they all agreed that this place is a marvellous place. I am already thinking of going back. I hope they continue like this, working as well as they do and maintaining this level of prices so that not only people with very high purchasing power can have access to it, as happens with other clinics of this style. On the other hand, I would like to comment that, in relation to my request not to have activities too early in the morning, although on the first day they organised the timetable without considering this request due to an internal organisation issue, they immediately reorganised everything to try to please me on this point as well, for which I was very grateful. Thanks also to you for the little gift of the bag and the bottle and even more for the massage.

We love this

  • Super friendly staff, most of whom have been working here for years, it´s a real family ran hotel
  • Amazing sea views from the mayority of the rooms, restaurant and outdoor pool/terrace
  • Super professional team, with the nutritionist, doctor and personal trainer working very closely together
  • One of the best Thalasso Spa´s in Spain. Sea water therapy!
  • New stylish beach club
  • Extensive Gym!

This not so much...

  • Style is very classic/traditional, might not appeal to everybody
  • Not all staff speak English
  • The beach is not right on the hotel´s doorstep, you have to walk a few minutes
  • The food is Mediteranean style, so pure flavours but maybe lacking spices for some people. We thought the macrobiotic food could be improved.
  • Hotel is closed in winter months

Our tips

  • Via verde, take one of the hotel bikes and cycle along what used to be the old train track path up the coast, the views are amazing!
