I will start with the less good :
- the hot water is a bit finicky, and we sometimes had to let the water run for a few minutes until the heater turned on and we got hot water.
- in the appartment that we were in, there was a bad sewer smell coming from behind the washing machine. It was not overpowering the entire appartment (probably also because there are multiple electric perfume diffusers in the appartment), but definitely noticeable when in the kitchen
- it is not very well insulated against noise. We did have issues sleeping one night when someone in the building, a few floors up, was having a big party.
- it didn't bother us, but the elevator stops at half-floors, and you still have a few steps to the appartment
What was good :
- the hosts where amazingly nice ! Thank you !
- the appartment is super well located, less than a 5min walk from the Sagrada Familia
- dogs are welcome with no additional cost
- great fast wifi
- fully equiped kitchen (except for an oven)
