The host is very welcoming and available for any concerns. There is a washing machine, towels, sheets, dishes, a TV, etc.
The apartment is very well located in Barcelona (center quickly accessible, supermarkets everywhere around, etc.).
However, there are several shortcomings: the shower is extremely small (a little overweight and you can't get in), the elevator is very old (although this is an essential point when you're on the 6th floor), in summer it's extremely hot (even with the windows open, it's too heavy and there's no ventilation) and unfortunately in the kitchen there was still some cleaning to be done (sticky cabinets, dirt behind the stove, etc.).
But it was a good help for our transit period :)
