We stayed at the Hotel Mar Y Luna for 5 days and it was a great experience. It is one street over from the main strip in town so it is quite at night and there is a great ice cream shop right across the street, there is also a little balcony upstairs that is great for sitting and people watching. For a double bed and ac we paid $26 a night, the room was worn but clean, just the basics, if your looking for anything more then a place to store your stuff during the day and crash at night this is not the place for you. The staff is all family and is super friendly and helpful, we had forgotten at our hotel in San Jose a very expense hardrive ($700) and the staff took the time to call several times and arrange to have it sent to us, couldn't do enough to help.

If you don`t look for something special but cheap this is a place to stay. We payed 31$ for a double room with hot shower and fan. The room was basic but clean. We stayed there for one night. Breakfast is not included but there are many places around where you can eat!
We really recommend this place if you look for a cheap option to visit Manuel Antonio. The park is a 25 minutes ride with the public bus or taxi away. Take the public bus, its cheaper and a really interesting experience!

A friend and I wanted to visit Manuel Antonio and found the hotels in Quepos a more economical option. Quepos is only a 25 minute (25 cent one-way) bus trip away from Manuel Antonio and considerably cheaper (especially since many of the hotels that advertize themselves as being in Manuel Antonio are actually anywhere along the road between Quepos and Manuel Antonio. Mar y Luna was an economical option in Quepos. The staff was friendly and the lobby had a TV that they let you change to what you wanted to watch. We had heard breakfast was complimentary but when we got there we found out it was only available during the dry season. We had a double with private bathroom for $20 dollars total per night. The room was nothing to look at but it was clean. It had two single beds and a shelf. While no air conditioning, the fan was very good and kept it bearable in the room. The bathroom was again nothing special and only had cold water but it was in the room.
