I booked this hotel because a colleague had stayed in it and said it was fine. I think that is how I would sum the hotel up... "fine/average/functional". There is no wow factor but it does the job.

It is aimed at the non-backpacker, mid-range market

San Pedro is purely a tourist town (but don't let that put you off, the town is bizarre, interesting and fun with fantastic craft shopping). The hotels therefore have no problem being filled and therefore any mid range hotel of this sort doesn't really have to try very hard.

The upsides:
The beds are comfortable,
The rooms are spacious and spotlessly clean,
There are heaters in the rooms (which was particularly lovely in May when it was freezing at night)
The staff are extremely helpful (although they won't ring anywhere to help you book anything - they just point you in the right direction).

The downsides:
Given that the prices in the rest of Chile are so reasonable this hotel was quite pricey for what you got in comparison.
The breakfast was fine (if a little basic) and if you are a minute late for breakfast it has all been cleared away and they won't bring it back.
The hotel is about a 7 minute walk from the centre of town. It's extremely safe but, particularly when it is cold in winter, it is a bit of a drag in the evening to walk in (in sub zero temperatures). This doesn't sound much but most of the other hotels are much closer in (although I suspect they may be quite noisy at night whereas the Don Tomas was very peaceful.
It's not a comfortable hotel where you can just chill out if you fancy a day/afternoon off sightseeing (which you may need if you do all the early morning tour trips!).

Would I stay there again? Possibly, although I might look for something a little more central which has somewhere comfortable to chill out for a couple of hours if you need to.

Last May my nephew and I went to Atacama. Since ours contacts by internet in order to arrange everything of our stay until our welcome reception and stay, the hotel´s staff were perfect.
Besides its location, charm, and infra, this hotel must be very proud of its staff.

This quiet hotel is just minutes walking distabce from San Pedro village. The hotel has different wings to it and our room was near the pool area. While the pool was very cold due to the season, the patio area around the pool was an excellent location to sit and enjoy the magnificent sunshine. The hotel has another patio area near the reception and breakfast room area. The room was quite large and very clean. The whole site was very clean and well looked after.

The staff was unfailngly friendly and most spoke english. The hotel offers tea and coffee on a complimentary basis all day. Breakfast was simple but wholesome. Since we left the hotel very early in the morning on two occasions, they prepared for us box breakfasts - a welcome surpise. While the hotel does not have a restaurant, it does offer sandwiches and hot food in the evenings if one does not want to walk into town.

San Pedro is a beautiful place to visit. The Tatio Geysers are a sight to see. We also visited an archeological site outside of the town.

We certainly would recommend this hotel. It is a peaceful and tranquil oasis within the oasis of San Pedro.

We stayed here as part of a group trip, and returned back to the hotel on 3 separarte occasions over a 10 day period. We were in different rooms each time, which were always clean and tidy and a welcome relief after our camping and refugios. Whilst away the hotel retained our unwanted luggage, which was always in our new rooms upon our return. The staff were really friendly and accommodating and nothing was too much trouble. The availability of tea and coffee (free), at all times is another nice touch, and in reality the hotel became a little home-from-home for all of us.. Breakfasts were also excellent with scrambled eggs etc. and constant replenishment of all items.
Although the hotel is about 250 metres from the main part of San Pedro, this was actually quite a nice walk, and caused no problems. It also means that the hotel is quiet. It does have a pool, although it takes some finding, but you don't stay here for a swimming pool. Overall a nice, friendly and comfortable base for exploring the area.
Also San Pedro de Atatcama is a really nice town with good restaurants and bars.
