I think it comes down to the level of comfort you want. I'm a budget traveler, who tends to stick to airbnb's (generally a private room). I tend to stick to the $60-100 (Canadian) range, sometimes getting into the $120 range. The one time we dropped a lot (for me) of money on a hotel - it was strictly for the convenience - we stayed at the Sofitel either Gatwick or Heathrow - I can't rem which - it was 10 yrs ago. It was up in the $175 price range - but we were taking a late flight from Venice that wasn't getting in til around midnight, and we just didn't want to mess with taxis. And the sad thing is - we barely enjoyed it because we didn't get to the room until after midnight, and prob left around 9am or so.
But we are fine staying in a private room. We def aren't the 'luxurious' type (tho I wouldn't turn my nose up at it). We like meeting people and have met some lovely airbnb hosts. One lady we've stayed with twice in Paris. Another one I'm hoping we can stay with again (stayed with her in 2015) for our upcoming travel.
I'm in the same frame of mind right now. Looking at booking places in Provence for July. We just decided last week to do this trip, and even now, finding something in my budget that is good is hard, because it's a very popular time to travel there. I had a very well meaning person send me a link to an airbnb - it was $265 (Can) a night - I'm like - that's my budget for 3 nights! I just can't bring myself to drop that kinda cash on somewhere we are most likely only going to sleep and eat breakfast.
My husband and I just really like meeting and talking to people - at a traditional B&B, we've had some great chats with folks over breakfast. At airbnb, we've had great chats and experiences with our hosts - I feel like we are connecting more, which we def don't get at a hotel.
You seem to be doing it right for you - you'll figure out which you like better. And sometimes a hotel is just what you need. We've never used hostels, so I can't speak to that, tho we did couchsurf some at the start of our travels, and have slept on some air mattresses, regular mattresses on the floor, and yes - even couches!
