I stayed there for a weekend trip. The house is same as in the pictures. Tomass was very helpful; he replied messages quickly and was very friendly. He even put some snacks in the kitchen and water etc for the quest which was a very kind act.
You can reach to the old town by walking like 25-30 minutes.
It had everything that i would need/use for a few days trip such as iron, shampoo, kitchen stuff etc.
I just felt a little cold at nights but not sure it is about the house or i am not used to this kind of cold weather in general. :)
I would recommend this home and also would probably stay there again if i come to Riga :)
