Belem is a nice little area with everything you need.
Ana's place is spotless. The beds are comfortable and the room was spacious that we stayed in. We loved the windows to look out of. At night they brought in road noise but if you shut them with shutters it cut alot of the noise. Bring earplugs if you are sensitive. The shower was great and kitchen had everything.
The restaurants were good and transportation was easy. Price was reasonable.
