Casa Wagner
There's a few things that let this hotel down, but only one was annoying enough to spoil my stay: mosquitoes. Not entirely the hotel's fault, but the constant bites were unpleasant, as was being woken up in the middle of the night by a high pitched buzzing. It also wasn't pleasant to have to keep the windows closed on warm, muggy evenings.
Don't get me wrong: it wasn't a plague of them, just a few, but they kept coming. I have no idea where from. The rest of the hotel is great, especially it's central location, the large, clean room, the cool courtyard, nice views and the comfy bed. It's also very good value. It only requires that you buy bug spray the first day you are there (the hotel would do well to supply a can for you).
But that's the other problem with the hotel. The staff are ok, and the service is acceptable, but they aren't particularly friendly or helpful. There's no effort to go the extra mile, or to think about things like "oh there's mosquitoes in here and that will be unpleasant for the guests - let's fix it." And these were big mosquitoes too.
If there had been a can of bug spray in the room on day one, this place would have got 4 or 5 stars from me...
