I stayed in this hotel for 2 nights and enjoyed it a lot. The service was great and everybody at the reception was very friendly and helpful. We had a room at the upper floor, which was simple but clean, comfortable and very spacious. The best part is the big balcony, with chairs, a table and a hammock in front of the rooms. From there you have a beautiful view to the garden and the sea, it is a perfect place to relax and I felt really well.
It is true that in the evenings it was a little bit noisy because the hotel is located direclty in town and close of restaurants and bars. Also in the morning the birds will wake you up but anyway its a good idea to get up early and to enjoy the beautiful sunrise from the balcony or the beach.
I have been in Montezuma 3 times now and always enjoy it. Already the way to get there is very nice especially crossing the Gulf of Nicoya by ferry.
In Montezuma there is so much to do and to see. The beaches are nice, several waterfalls can be visited, the town offers many different very good restaurants (I recommend the Soda Montesol, which offers great typical breakfast and delicious Casados), souvenir shops and bars.
When you're planning to stay in Montezuma for several days I also recommend to visit the Cabo Blanco reserve which is easy to reach by bus from Montezuma (bus leaves at 8am and I think every 2 hours). It is a great place for hiking in the forest and you can spot many different animals, butterflies and especially howler monkeys.
