Loi Suites Arenales is a 76-room apartment-style hotel by the lush and leafy Plaza San Martin in Retiro. Although there are shopping thoroughfares, historical landmarks, and museums just a few streets away, the immediate area is quaint and quiet. Rooms are comfortable and have kitchenettes, but overall the decor could use some color as well as an update in certain areas (mainly bathroom fixtures). Overall, rates are affordable but amenities are scarce -- just free continental breakfast and free Wi-Fi (only in the public areas).
