There isn't a better location near the Alamo and River Walk (within a reasonable price). You can walk everywhere from this hotel (The Alamo is just across the street.). My room was very spacious with a big window for lots of natural light (I like that). There was no frig or microwave; but, there was a coffee pot. There is free wi-fi. There's a good (complimentary) breakfast in the morning. The breakfast area was well-stocked and clean. The staff is welcoming and friendly.
My room was very clean and fresh with a comfortable bed. Everything was perfect.
The one thing is, you have no option but to valet your car (for $21 a day). But, like I said, the Alamo, River Walk, the River Walk Mall tons of shops - everything is within walking distance of this hotel - about a block away, so you won't need your car for those things. This seems like a very safe neighborhood for walking around. (I can't say that FOR SURE, but I didn't have any problems at all - seemed safe to me.)
I also visited some Missions (National Park sites), but they are farther away. So, this location is not near those at all. (Be sure to drive out and see the missions if you are here - don't miss them; they are beautiful.)
A great stay - and I would definitely stay here again when visiting San Antonio. You can't beat location and price.
Some San Antonio advice: Be sure to take one of those River Walk little river cruises. It's a lot of fun and you get some history on the river. It's only $8 and takes about 45 minutes - I was so glad I did it.
