We spent three nights in Manuel Antonio and decided to stay at Villas Lirio. Check in was OK, friendly staff and good informations about the hotel and park (go early, guide is not neccessary).
The good things first: Rooms were clean and quite, the staff very efficient, friendly and helpful. The place has got many restaurants around.
Rooms and parking place were really tight, and very dark. The infrastructure was rather old and old-fashioned, WIFI was not working in the room. The breakfast was extremely simple and tasteless (you passed the kitchen smelling good and then: just boring food). Also you were forced to wear a color armwrist, which reminded of an all-inclusive hotel.
