True to its name (Hostal Arco Iris means Rainbow Guest House), this small hotel is colorful and modern. It was obviously remodeled a few years ago to good effect and the rooms are comfortable and contemporarily decorated. The single and double rooms are available with a private bath or a shared bath. There's free Wi-Fi and an Internet station in the hallway. Retiro Park is nearby.
