Acacia Boutique Hotel is a strange combination of charm, old, very budget and simple, and high-end due to its excellent restaurant. I stayed for one night in between more luxury hotels and I don't plan to stay here again on future trips to San Juan.
For military and government folks, you may understand when I describe this establishment as 'military lodging' on a beach base. That's totally the feeling I got from Acacia.
That being said, it's not terrible by any means! However, if you're one that enjoys more luxurious types of service, and modern and clean rooms and grounds... do not stay here. This is definitely lodging for those on a budget.
Room -- We were booked for a standard room, but upon check-in, were upgraded to a king. The room is verryyy simple. The AC was not on when we arrived at our room, so it was very stuffy. We turned on the AC right away and it is one of those older loud ACs that sounds like it's rattling. We had a decent bed... it's sort of like a motel bed with dry/hard sheets and pillows. There is a dresser and a small coffee table and two small chairs... The bathroom is similarly very simple and offered just small soaps (the kind you'd find in a motel), a shower cap, and cheap shampoo/conditioner. The AC doesn't reach the bathroom so it is warm inside...
Hot tub -- Many folks talked about the hot tub. We didn't try it, but it looked very nice. It is indeed large.
TV -- TV has poor sound, but the size was fine. It was a flat screen above the coffee table, underneath the AC. I had a hard time hearing any dialogue on the TV due to the rattling of the AC.
Location -- If you like the beach, this is a great location! It takes perhaps 30-60 seconds to walk to the beach from the hotel entrance. We took a walk before dinner and it is a nice beach where we saw many locals enjoying their weekends. And to restaurants and bars on the main Ashford Avenue, it takes just a few minutes. Otherwise, Acacia is tucked away in a quiet neighborhood.
Staff -- Each member of the staff was very kind and helpful. Christopher has good food recommendations.
Restaurant -- Niche is a great restaurant... very strange that an expensive restaurant is located inside a budget hotel... Chef David from France is so attentive and personable, really appreciated his keen eye for detail.
I recommend staying here if you are on a tight budget or need to squeeze in a hotel in between others like we did. If you don't mind a budget feel with some discomfort (AC is a big dealbreaker for me... and having a hot and stuff bathroom...no...), then by all means, stay here and I think you will enjoy it. However, if you are more into the cleaner, more modern hotels... go elsewhere.
One more tip: Acacia is near Cafe del Loto, a nice coffeeshop that serves great coffee and food. (Not even a 5-minute walk.)
