hotel kevin is an other Option (search in facebook: hotel kevin puerto plata).
I only stayed in Mountainview and the rooms are good, you don't have a swimming pool and the neighborhood is not the best, but I would stay there again if I needed to
The other ones, I can only say what I heard from my clients, I didn't tried them myself, but as a bar owner I hear a lot:
- Lomar:
Pro's:
at the malecon
Swimming pool
Security at night
Good price
Con's:
Outdated chambers
Portofino:
Pro's:
Close to the malecon
Swimming pool
Con's:
Nobody that I know was happy there. The owner treats the customers rude, prices are high if he knows you are a tourist, chambers are not good, food is terrible
Kevin:
Pro's:
Honest owner
Good price
Con's:
Not at the malcon
If I have friends asking, I would send them to lomar or kevin, maybe mountainview if they speak a bit of Spanish so that they can take a motoconjo
