Nice place, but uncomfortable cohabitating with Julián, the host. There are a lot of rules in the space: some stated, some unspoken; some logical, some nonsensical. And when I inevitably broke the unstated rules, I was met with eye rolls and sighs, leaving me feeling unwelcome in the space. Some stated rules: clean the toilet after every use; mop the bathroom floor after every shower. Some unstated rules: don't enter the kitchen when someone else is in there (this had nothing to do with Covid--I asked); don't set (my own) clean kitchen supplies on a kitchen counter that hadn't been cleaned yet. Lights and tap water were turned off while I was using them. The host knocked on my bedroom door after midnight to give me a new fan, which I felt was inappropriate timing. If I encountered Julián in a hallway when we both needed to go in the kitchen or bathroom, he would sigh, roll his eyes, and let me pass. Ultimately, it appeared as though Julián did not want guests in his home, despite inviting them in.
The space itself was nice, though very hot (no AC, which seems to be pretty common in Valencia). I was permitted to run the fan any time I was in the room, which I appreciated. Nice desk with soft chair to work from in the spacious and thoughtfully-decorated bedroom, in a quiet, well-located neighborhood. Fast internet: 132 Mbps download/180 Mbps upload speed. I was not allowed access to the living room. Also, I didn't love that the bedroom door was glass--frosted in some parts but not in others. A nice piece of fabric or a curtain over the glass would have added some privacy.
The space is nice, and the listing has potential if Julián tries to be a more welcoming host. He's clearly dedicated to keeping a nice house, so I'm sure the next guest won't have the same problems I did.
