The H Hotel is a serviceable stay for Munich visitors on a budget who aren't looking for any frills. My wife and I stayed 4 nights and had a sufficiently spacious room that was dated but offered areas for us to lay out our belongings. The bathroom was more cramped than we preferred, but the shower was great (just make sure you close the doors carefully to seal them).
The wifi was great, and the air conditioning in our room was fantastic--some of the best in our 2.5 week European vacation. We really appreciated it after our hot, muggy days exploring the city.
The hotel itself is located conveniently close to Old Town, and is less than 10 minutes walking distance from the main train station. It's a little longer to the Munich Central Bus Station--about 25 minutes walking. For the convenience of proximity, the pricing was a good value. One thing to note is that the actual neighborhood around this hotel may not be ideal for families, as it is noisy, dirty (we saw human feces on the streets on 2 occasions), and has many strip clubs. On the other hand, if you want a place loaded with great Middle Eastern restaurants, this is a great neighborhood for that.
Overall, a solid hotel and worth it if you have pragmatic expectations.
