That $8 Lisbon hostel bed ruined my whole week, take the extra train
I booked a super cheap spot in Alfama near the cathedral, figured 8 euros was a steal. Turns out the bunk above me squeaked every time someone breathed, and the shared bathroom line at 7am had like 12 people in it. Missed my 9:40 train to Sintra because I was waiting to brush my teeth, ended up paying 14 for a later one anyway. Anyone else learn the hard way that saving 5 bucks on a bed costs you more in time and sanity?
Went through the same thing in Porto a couple years back. What finally worked for me was booking the slightly pricier places but only for the nights before big travel days, then going cheap on the lazy days where I had nothing planned. Sounds dumb but it saved my mood way more than the few euros were worth. Also started showering at night instead of the morning since the bathroom rush is always worse before 8. Sleeping in a quiet room beats saving 5 bucks every single time.
