All the important things at this apartment were great: the beds were comfortable, the shower was good, everything (except the oven) was really clean, the location was great, the internet worked fine for us, the apartment was neat and minimalist. The woman who gave us the keys was really friendly and helpful too.
We never met Eduardo, but when we had a problem with the safe in the kitchen we contacted the hotel where we picked up the keys, and they sent someone to fix it the next morning first thing, and sent a bottle of wine too, which was really kind.
The only things which could be improved were that there were a lot of mosquitoes which made it hard to sleep at night, and there was no bug spray or anything to stop them. There wasn't much equipment in the kitchen, only the minimum - and the kettle shorted out the electrics so we didn't use that. And no serving bowls, mats, oven trays etc. This wasn't a problem for us, but if you wanted to do more cooking or there were 6 of you it might be.
There was also no local information, so we didn't know what stuff we could recycle and where, and where the shops were etc. Again - not a problem just something that could be done.
There are lots of playgrounds nearby (and an easy walk to the Parc de la Ciutadella and the beach) which made it a great place to be with a small kid too, and she also loved the bunkbeds and eating supper on the balcony.
