The location was perfect. On a side street, opposite 2 cafés, 50 metres from a supermarket, and a few moments walk from bus, metro station, and several good places to eat. Also south facing, so cool in summer, and plenty of hot water.
Less than perfect, the cleanliness and maintenance. Certain parts were just dirty and neglected (we had to employ a cleaner). There were 2 wall mirrors badly cracked, window blinds were broken, and we had to replace 4 light bulbs.
The only problem that arose was that the TV wasn't working at first, but Nicolás responded quickly and got it fixed.
But best of all, the bed was quite literally the most comfortable we'd ever slept on.
So we'd stay here again, but with a little more care it would go from promising to excellent.
