Stayed here a couple of times when passing through San José. Rooms are comfortable and spotlessly clean, with hot showers that work (and don't electrocute you, like some in Central America!), good mattresses and space to unpack a little.
The hosts speak Spanish, English and German and can help with travel enquiries such as bus times.
There are several restaurants close by, and the area feels safe enough to walk for short distances even at night. It's also close to the shopping areas and museums. It's a bit of a hike to the bus stations, but doable if you don't mind a walk, or it wouldn't cost much in a taxi.
We didn't have breakfast there, but there are a couple of bakeries nearby for a coffee and pastry.
Only issue might be the train noise for some people as it's next to a railway line and the trains hoot as they go past, but we got used to it pretty quickly.
