This place was like it's own mini oasis in the middle of San Telmo. From the outside you may easily walk past it but once you get inside it is all modern and has a great little cafe and pool for communal use on the first floor. There is also an elevator in case you have bags that aren't easily carried up and down the stairs.
The bed was great and easily fit a 6'3" guy. The small kitchenet has everything you need to cook if you so choose. The bathroom was bigger than most bathrooms we had seen for Buenos Aires and came fully stocked with towels and soaps. There were plenty of plugs around the room and a full length mirror in the livingroom enabled you to get ready in the morning while someone was in the bathroom.
The front desk is very friendly and will even help you with directions and book dinner reservations. If you arrive early before check in or have a later flight they will let you store your bags in the lobby.
Internet speed was great and A/C unit worked just fine. This place was recommended by a friend and I would for sure stay here again!
