We only stayed for one night at Greenspace Palawan but would have loved to stay longer. The design of the hotel is great - very modern and light. The rooms incl. bathroom were spacious, clean and modern with enough space to unpack your backpack. The bed was soooo comfy! The staff was very friendly, helpful and the breakfast was really good. It is in a calm side street from the noisy main street, which was really good. So only a few minutes walk away from all the bars, restaurant, etc., however, very calm.
Definitely a place to recommend for a stay in Puerto Princesa!
