Arco Iris had a great feel to it. The pool is very nice. Richard is a super cool guy and is extremely friendly. We had to leave at 4:00 am to catch our flight and Richard gave us some fruit, muffins, and juice. He offered that up without us even asking. We were very happy with the location. You are just far enough from the noise of the main street, but still able to walk to everything. The beach is maybe a 5 minute walk. There is a walking path from the hotel to a road with tons of great restaurants. If you feel like staying in for a nice meal, they lease their dining space to one of the best restaurants in Tamarindo, Seasons by Shlomy. We traveled to 4 different cities in Costa Rica and this hotel was our favorite by far. The air conditioner in our room was kind of weak. It worked a little better at night. We weren't around much during the day so it didn't bother us much.
Nothing The place was disgusting, I should had listen to reviews bout rooms not being clean but I gave it the benefit of doubt. First the pillows had hair on them, the towels in the bathroom were like stain with paint or something and worse part is the bathroom smelled like week old sweaty clothes( not exaggerating). There was a shirt hanging on curtains from previous guest. There was a fridge but it didn't work! I left the place, there was no way I could sleep there let alone shower and use those towels. The pics are deceiving and I don't know who reviewed this place but my experience was. Awful!
Hotel Luna Llena was amazing we were traveling with a 8 month old so we really enjoyed the quiet setting, just a block away from the beach and the main part of Tamarindo, we had a car rented but didnt have to drive unless we left town. Clean rooms and friendly staff we stayed in bungalow 6, it had a loft with two twin beds and the main floor had a king bed with a kitchen and bathroom. Cable TV, we don't speak spanish but was good to have cartoons for the little one. All the rooms are centered around the pool offering food and drinks from noon-3 and 6-9PM. The landscaping was very nice, providing privacy, quiet and just a calm vibe, very relaxing, we enjoyed spending time there. Wifi signal was weak in the room, good around the pool. Beds were a little too hard for our liking.
