We enjoyed our stay at Victor's apartment in Barcelona. The location is great, on the edge of the Raval and within easy walking or metro distance of everywhere we wanted to go, and we felt quite safe in the neighborhood. The apartment had a comfortable bed and sitting area, as well as everything we needed in the kitchen. It was very quiet, even when there was activity on the street. TV, wifi, heat, appliances, etc. all worked well.
Cons: Upon our arrival, we had to wait outside in the rain for 20 minutes after our arranged check-in time for someone to come and let us in. It was December, and cold, and we had been traveling for 17 hours, so that was a problem for us.
We had some minor complaints about the bathroom: when you shower, the water gets all over the floor and makes a mess. Also, the towels were a bit smelly, even after we washed them.
Finally, the ad states that the apartment has a washer and dryer, but there was no dryer.
Overall, a good experience with a few inconveniences.
