There really wasn't anything special that I did not like. Of course the location depends on your needs. If this is far away from the places you plan to visit while in the city, then you might consider staying somewhere closer to that, as you will save a lot of money travelling back and forth. Also keep in mind that this is a budget hotel, so if you are accustomed to luxury, you might be disappointed. The bed was hard, but that is a taste issue, so for me it was acceptable.
Nice and clean rooms, good restaurant with very low prices. The staff did not speak English very well, but fortunately I know enough Spanish so communication was no problem. Staff was friendly and polite. Check-in was very fast and easy, no ID required or any papers to sign, since I already booked via booking.com. Took about 1 minute from I arrived until I had my room key. Nice shower with plenty of hot running water. Very big bed. A taxi ride from the hotel to La Merced was about 25 pesos (US $2, €1,5), a 5 minute ride depending on traffic. All in all very good value for the low price of this hotel.
