This hotel is really different, everything is built to keep the authenticity of the place. It is built in an old monastery, very well taken care, and with the minimum of modern things. So, it has great historical value, the building is beautiful - it looks great in pictures as you can see in the site, BUT it lacks the kind of confort I'm used and enjoy.
I rented the suite, that is just beautiful: a big bedroom, with a very good bed and pillows, and a real fireplace. In the living room, too sofas with a blanket (really cozy), another bigger fireplace, and a big bathroom (no fireplace, so it was much colder, even if you let the small heater always on). The fireplaces were already heated, but we have to maintain them by yourself, feeding logs that were already in the room. All the woods (doors and the ceillings) looked original and very well taken care of, and also the walls showed the original stones, keeping the original atmosphere of the place. BUT no more of modern commodities: no TV, no minibar, no A/C. I would expect from a Arteh hotels at least to include a bathrobe, slippers, laundry bag, more WC items (only provided shower gel)...
It's very difficult to criticie, because I understand the value of it all, and it really looks perfect in pictures, BUT I would feel more confortable wih some more modern comodities - it is design for autheticity and to provide rest (and it is really peacefull).
The hotel has a small pool,a reading room, a very good restaurant (no BUT in the restaurant, nice atmosphere, nice food). The breakfast were served until 12, and the food was very genuine and very good (look at the milk pots, really antiques...) BUT I would expect ham, cheese and eggs to be included at no extra cost.
The location is really quite, BUT nothing to see around, the nearest big enough towns are more than 50KMs away.
I like very much cars, so I'll use the image; this hotel is like a Classic Car, rebuilt respecting all the original parts, with only small alterations to make it drivable in modern roads - it is beautifull , has a lot of value, but I prefer to drive a modern one, with all the luxury and modern comodities I could afford for the money I paid (185€ per night).
I can recommend two other places in Portugal, cheaper and more confortable (not as close to the original, but in my opinion, with a better ratio confort/charm) that you can also take a look: Monte do Carmo in AZARUJA (I already reviewed it in tripadvisor - has the advantage of being close to Evora) and Hotel Forte S. Joao (http://forte.com.pt/ - this one is 13KMs from Porto).
