Airbnb has certain advantages over a hotel that justify the similar or higher prices with less/different services than a hotel would offer. One of those is the amenities like washers/dryers. In this case, the dryer was broken so one of the crucial points for me was unavailable, which really affected my plans.
The distribution of the small lodging is very awkward and there's almost no room for clothes.
I'm not sure if it's a problem with what's available in Dublin but I was generally not impressed with what I saw in comparison with what was advertised, at that price. I felt I would've been more comfortable in a traditional hotel setting than this, since I didn't end up using any of the typical Airbnb amenities due to lack of comfort.
The area is not particular nice either, specially walking in at night, although it's conveniently located.
Reception staff was very friendly.
Sonder as an app/system, seemed to create a lot of bureaucracy but then offer very little in return to justify the hassle.
Overall, I feel it wasn't worth it.
