This place has a lot going for it and some going against it! Firstly, it is light and airy (although stuffy when I arrived - the windows and french doors need to be opened to let fresh air in). The foliage on the deck and the green of the park outside are wonderful - but attract many flying and crawling insects which "bugged" me much of the time.
It is a bit misleading to describe the location as San Telmo - it isn't. Barracas is where the property is located - at least 2 kilometers from San Telmo. A great walk if that's what you want.
The stairs up to the room are steep - not a problem if you have a backpack or no luggage but not so easy to negotiate with suitcases.
It is also a stretch to call this an entire home. If you don't want to cook at all then the fridge and microwave are useful - but can't consider this a kitchen. One point to clear up is the lack of glasses for water, wine or any other drink.
The bed is comfortable - very comfortable. I slept well - after the first night (the traffic noise from the highway just across the park was quite disturbing to begin with).
All of that said, I liked being here. It is a tranquil space. Just a bit too out of the way.
