The staff is professional and willing to help with whatever arrangement you need. My room was quite spacious, there was a good selection of channels on the cable system, the desk was nice to work at and the internet was fast.
Plenty of hot water and all of the amenities you need in the bathroom. I arrived after dark and left around dawn so I didn't get to explore the backyard much but from what I saw it was nice. The hotel itself was in great shape, well maintained and clean, with a kitchen available to guests. When I left the hotel at 4:30 am a staff member met me at my room with a brown bag breakfast to go that was fairly substantial.
As a friend was traveling to Guatemala after me and following me to San Marcos and spoke no Spanish, I was able to get the hotel to pick him up from the airport, drop him off at the bus terminal and even pick him up from the bus terminal upon his return eight days later.
You'd be hard pressed to find better service.
