Hi there,
If are
looking for a private swimming pool, you are looking at apart hotels, which is best of both worlds, rather than Hotels. Apart hotels usually come with their own private swimming pool.
The Green Park Golf del Sur in
Tenerife is a good example featuring modern amenities such as TV, fridge, etc. It has a large balcony overlooking its three private pools.
Another choice would be
Aparthotel Los Geranios which is located in the San Eugenio area of Costa Adeje. It consists of a studio and one-bedroom apartments including amenities such as telephone, bathroom, satellite TV, etc.
Hope this helps
