*** Hotel reviews are based on the category of the hotel, I do not compare small B&B's to massive hotels as both can be excellent in their respective categories.

We have stayed at this place a couple times before and reviewed it then as well. Happy to report that this place is still a great place to stay.

It's a simple, clean, and affordable place to stay on the beach, and in the middle of everything. Rooms are clean and comfortable, the staff are friendly, and the view is quite nice as well:)

I recommend staying on the second floor as the veranda is nicer to relax on.

Only negative is it can be a bit louder outside at night on the weekends due to it's proximity to some bars, we however slept very well every night.

Conch Shell has a wonderful location, rooms are fantastic (CLEAN) and just the right size. The view is beautiful HOWEVER the staff and ownership could stand to revamp how they conduct buisness. We were given a GREAT deal on our room (we recommend staying upstairs by the way both for privacy and the view) BUT.... what we weren't told about why we were given such a killer deal on our room is: the laundry facilities are broken (the manager thought that was funny and didn't make any effort to help us find somewhere else to wash our clothes; a 15 day stay will invoke the need to wash clothes) and worst of all our ENTIRE stay was wrought with the sound of hammering and sawing ALLLL day because the hotel is undergoing renovations (you can count out any hope of taking a nap in your room mid day.) Our first night there we had no toilet paper and when we ran out house keeping didn't feel the need to provide it- we had to ask for it. House keeping only comes at about noon, if you're in your room then you will have to specify YES I would like my room cleaned/sheets changed etc. However, in stark contrast to this downfall, the management was more than helpful and friendly in helping us make wedding arrangements and the JP was more than perfect to us and for our ceremony. So the ammenities and location are FANTASTIC, and the rooms are clean and beautiful BUT the experience of being a guest at this hotel is a little rough around the edges when you can't even get toilet paper without waking up housekeeping at 6am to make a point that it should have been provided the night before. Neither the owner nor the management are very knowledgable about the surrounding area either; the laundry facility is broke and won't be fixed any time soon yet they can't tell you where to find a place to make up for this short coming (the place they pointed us to has been closed for some time.) Given we both come from a military background we can easily make up for these little hiccups and would be willing to consider staying here again but definitely NOT for the price advertised and not without asking some questions first.
Wifi is provided, but it can be PAINFULLY slow and goes down just about every morning. If you're on vacation this shouldn't be a big deal, but it's nice to know ahead of time. Skype is also blocked in Belize, so if you need to phone home for any reason have an alternate plan or just use email from your room.
The rooms have mosquito netting on the windows (though ours has some holes in it which didn't seem to be a real big problem- but its the little things) and two perfect fans to keep you comfortable. The porch set up is lovely and the hammocs provided are a GREAT way to end the day... just make sure to ask questions before you book.
If we had it to do over again, we wouldn't neccessarily change the location of our stay or the beauty we see from our porch, but we would have insisted on a lower price for the gross inconvenience of the construction on the other side of our wall. We feel the owner lied to us/kept the information from us in order to guarentee revenue in the slow season when we should have been told all the facts about our pending stay with the hotel.

My husband and I stayed just for two nights as were vacationing in mexico for few weeks and came down for some snorkeling. Conch shell was perfect, clean, affordable and close to everything. For the little amount of time we were there the location was perfect, being able to walk the whole town. Lovely large veranda with big chairs and tables on the beach front and loungers right on the beach. The early noise did not bother us nor did the late night/all night noise. Oct is not the time to visit as many of the recommended places we wanted to visit were not open. We would stay here again.

Best location in downtown San Pedro. Just a few blocks from the plaza and both Ecological divers and Amigos del Mar within sight.
Beds were comfortable, no bugs, cleaning every day, very friendly staff who were more than helpful with everything. Quiet at night and with mosquito nets for all windows!
Would definitely recommend this place and would love to come back!!
