"Relatively quiet location and spacious rooms"
I have stayed at this location on many occasions over the past 4 or 5 years. Mostly for three reasons:
1) It's proximity to the main transit station Retiro (train station) - it's a short walk to this station.
2) Depending upon the room location, it is mostly quiet, as compared to other locations in Barrios Centro and Micro Centro. At many other locations, traffic/street noise will "invade" the room...
3) Dedicated Wi-Fi in each room (essential for me, for my work). No shared Wi-Fi like in a hotel...
This is not a regular hotel, per say - it is what I call an "Aparthotel". There is no room service, no on premise restaurant or business services, and room cleaning is only once a week.
If one takes a room at this location, one has to be prepared to go to the neighborhood grocery and/or Kiosks to obtain water/soda, coffee (to make in the room), snacks, etc. There is a kitchen to make food too - but I personally use restaurants. No laundry service, per say but there are washer and dryers available in the building - one needs to purchase tokens, from the Portero, to use these machines. Rooms are cleaned once a week, not daily like a regular hotel. Staff consists of one person in an office on the top floor, which is open in the mornings.
If one has extremely limited Spanish language skills (or none), and/or no real experience in Buenos Aires then I would recommend staying at a regular hotel. Otherwise this is a very good place with good rates.
