I visisted 10 of the 14 monasteries from the 16 century in the slopes of the Popocatepetl in Morelos and here is waht I found:
a) San Mateo Apostol in Atlatlauhcan: Not so bas conservate, but it needs work
2) de la Natividad in Tepoztlán: Is one of the most well taken care off and in reconstruction
3) San Juan Bautista in Tetela del Volcán: It's conditions are the worst
4) San Juan Bautista in Tlayacapan: Very nice, but it still needs reconstruction
5) Santo Domingo de Guzmán in Hueyapan: This is in the worst state. I couldn't even enter because it was really early, for what I saw from the outside it has been painted in pastel colors!
6) San Guillermo in Totolapan: I almost cried when I saw it. The upper floor has been remodelated to serve as rooms for he priests so all the frescoes are lost.
7) Santo Domingo in Oaxtepec: Very nice
8) Santo Domingo in Yecapixtla: Taken care off, but it needs work
9) Santiago Apóstol in Ocuituco: Nice, but is not very cared
10)Inmaculada Concepción in Zacualpan de Amilpas: It needs more work, although is in very good state
