it's OK. the location is good, a little out of the tourist city, but near enough and nice tapas places nearby and not too loud.
the property itself isn't really set up for living, there were little items e.g. kitchen paper that are needed for stays. only one kitchen towel, so if you stay for a week you need to do laundry, which is not in the house. there's also some quite strange art in the property.
WiFi isn't great and I had many problems working remotely when joining calls.
smell and noise traveled a lot in the building, so it wasn't pleasant to stay in and work from the house.
I've stayed in many other properties in Barcelona while working remotely, and found all other places offered much more value for price, and were more liveable for short or medium stays than this one. also, WiFi was an issue.
