It can often still have better range, even within an apartment building, since 2.4GHz will penetrates walls easier.
However, interference can be different, because 5Ghz has more channels, and many devices still primarily operate on 2.4GHz instead of 5GHz, meaning 5GHz can be interfered with less than 2.4GHz.
At the end of the day, it will depend on your environment, as interference can be a big factor, but regardless, you’ll almost always find you have better, consistent signal range with 2.4GHz than 5GHz, because it’s just that much better at penetrating solid objects, irrespective of interference.
Correct me if I’m wrong, but I believe that 5ghz can use higher signal power than 2.4ghz which would diminish this advantage by some, anyway. If I remember correctly, the 2.4 GHZ band is limited to 0.1W while the 5 GHZ band is 1W.
Edit: With that said, I’m betting that a phone hotspot limits both of them to a very low power in order to keep battery life because blasting out one watt would kill your battery quite quickly.

The allowed transmit power can vary by country, but I doubt any phone will use 1000mW for it’s mobile hotapot.
