Ok, let's make it clear that this is neither a Western-style hotel, so don't expect the facilities associated to those properties. This is a very nice guesthouse located in a renovated traditional house; reservations can be arranged by e-mail (not that common an option when dealing with Iranian hotels) and once you get there the female staff is all smiles and ready to cater for all your needs. We opted with a room with a shower and bathroom and I must admit it was very nice: huge ceilings, very comfortable double bed (no news of the hard mattresses some users complained about here), clean and nicely appointed, with A/C and a heater; we did use the latter as it can get quite cold in Kashan at this time of the year.
The bathroom was clean and spacious, and again contrary to what other users comment I found (and used) hot water to spare.
The house itself is beautiful, esp. the courtyard, and I was lucky enough to meet a bunch of very interesting people, Iranian and foreign, there. It comes across as incredibly serene in the early morning and night.
Breakfast is indeed very basic, but the nan is magnificent, probably the best we had in Iran, and that is a lot to say. Dinner is very nice, though, no traces of oil-soaking aubergine but rather a very smooth one. Chicken, meat and vegetable dishes, all well prepared and at laughable prices.
So to sum up, althoug basic this comes out as a very cozy place to stay in Kashan, a very interesting town by the way. Given the limited choice and the absence of top-end accomodation, this is a very reccomendable guesthouse.
