A point-set topology book that students seem to love is Topology without Tears by Sidney A. It seems to cover a large range of topics, which is nice. For the same reason, intuitive arguments have I would even say crippled the speed at which I could otherwise read texts, which I understand is the opposite of what most people would say.

Of course every mathematician should verify a claim until he feels comfortable that if necessary, he could produce the real argument down to the atomic details. From chapter 5 and on it provides one of the most modern theoretical works in Topology and group theory and their inter-relationships.

I’m assuming that the students are not familiar with point-set topology and it’s tpology first course in topology for them.
