My girlfriend & I stayed with Arturo & Elias during the Grito & Día de la Independencia. It was a perfect location, close to the Centro but not too close, & blocks away from Barrio Chino (where we ate often) & the Mercado de San Juan. Great value as far as location goes. You should be aware of the type of airbnb it is, though - it is more like a roommate scenario than a Bed & Breakfast, in an older apartment with a shared bathroom that has good hot water but is not the cleanest (recommend bringing shower shoes), a very warm bedroom lacking a fan, & a lot of street noise through the night. The hosts are very friendly, though, & even invited us to join their Grito celebration & firework viewing on the rooftop. Would recommend to budget travelers who value location over comfort.
