I'm feeling tense

I'm confused more so than usual. I'm trying to write Megan's thirty in first person present tense but i have no idea if I'm writing present tense, past tense or both.
Here's an example excuse the language


e.g The first place Olivia took me to was a complete shit hole. (Past/present?)


Now the next sentence goes:


it was worse than my seventies flat and that was saying something. (Past/Present?)


now should this sentence be as follows if I'm writing in present:


it looks worse than my seventies flat and that's saying something.


If it is then does it go with the first sentence as i don't think it does and i have no idea how to change it I'm confused Help!!
