First off this hotel is adorable! It is just as it looks in the photos, and the location can't be beat. But there are a few drawbacks, so I'll break it down as follows:
PROs: Unbelievably cute small hotel, and at a really good price. When I booked my room I made sure the owner knew I was a single person (I think I said it three times in my e-mail) but I wanted a balcony for sure, so if that meant I had to pay for a double room I would gladly. So he booked a double room for me with balcony, for the price of 44.94 euros per night rather than the 32.10 euros for a single. However when I arrived, he insisted I look at a single room, telling me he didn't realize I was only one person, since he had a single room with a balcony over a little side street. Excellent, I told him I would take it and said that my price would be the single rate, correct? Nope, I was still on the hook for 44.94 double rate he told me, but they would now include breakfast for the three mornings I would be there. Well, I don't usually pay over 12 euros for breakfast...but I was tired...didn't feel like haggling, and to be honest, 44.94 euros did seem like an okay price. The interaction did leave me feeling a bit unsettled though, but I was the one who agreed to it so...so be it! (This turns into a big CON later though as the breakfast was them completely ignoring me in their empty eating area every morning, eventually they would bring me one cup of coffee and a big hunk of bread with some jam. Then when I finished that I would have to hunt them down for a second cup of coffee, and I was very brave on days 2 and 3 to ask for a glass of orange juice, which given to me, but nothing close to service with a smile.)
But back to the PROs: I liked my little single room a lot. It had its own bathroom, was *just* big enough and I had my own set of French doors (no bars across) and small balcony that overlooked a side street that was barely wide enough for cars to pass. (I stayed in room 4.) Not much traffic, not too noisy. Good people watching. In addition, the hotel has a completely picturesque patio where you can get tapas and a drink on a nice day. (Although another CON wedged in here is that the one day I sat out there and ordered tapas, it took almost an hour just to get my small plate of patatas bravas. But hey, I'm in Spain and in no hurry fortunately...but be warned that service just seemed painfully and exceptionally slow for any kind of food.)
More PROs: They have a cute small resident dog, and if you're there on a Saturday night it seems like all of Cordoba is stopping by for a drink and socializing. I loved it! It was about a 5-minute walk to the Mezquita, and I felt totally safe out at all hours walking those streets. People in Cordoba were friendly and it was fun. And did I mention how picturesque the hotel is?
CONs: Management was laissez-faire and as others have noted elsewhere, seemed more interested in the locals in their little pub/restaurant than in their hotel customers. I definitely got the impression they wanted to have as little interaction with the hotel guests as possible. But it's okay, just give me the key to my room and that's usually all I need, so it wasn't a problem for me! (Well, except in the morning when I had to track them down for the extra coffee. One needs to pick one's battles and getting enough coffee in the morning is definitely mine!)
Also the door handle on my cute French doors was broken but it still locked and if I jiggled it I could work it okay. And this one killed me: The hairdryer they advertise is really a wall hand dryer that has a picture of a hairdryer on it. And it's mounted over the sink! I laugh every time I think of the contortions I had to perform to get my head under that thing, it really had no hose or nozzle or anything, just hot air shooting down onto the sink, and as I am somebody who requires a hair dryer after my shower, this provided much entertainment value every morning. I've been all over the US and to Europe 18 times now and have never seen anything like it. Too funny!
Bottom line: Despite the cons would definitely return to Cordoba and Hotel Plateros, but would plan to not eat breakfast at the hotel, and to bring my own hairdryer!
