My family (my wife plus two babies of 2 and 15 months) spent last weekend in Salamanca. We wanted a great atmosphere to relax in a beautiful city not far from Madrid (max two hours drive). After some research we found this hotel. It was a great experience. It has a small but more than enough SPA that for 40€ you can book exclusively for your use. In addition the hotel would provide different services as a fisoterapist, a baby sitter for the kids, etc.
The service absolute gentle and nothing was difficult for them. everything served with a smile. Perfect location (5 minutes away from Plaza Mayor, Cathedral or old university) but in a very quite and relax street just in front of a beautiful convent.
the Hotel has only 17/19 rooms. if you can try to book the one in the third floor since it is the only room in the whole floor so the privacy atmosphere will be even greater.
The hotel is placed in a old mannor house, and they have been able to keep all the historical beauty but with the most modern rooms and facilities.
With no doubt a safe recomendation.
