I stayed for three nights in this apartment and everything was lovely. The place was absolutely spotless. The shower was an absolute delight: lots of high-pressure hot water that starts quickly.
The hosts were professional and wonderfully accommodating of my uncertain arrival time. Maps and city info are available.
The kitchen is well equipped with everything you could want for a short stay. A grocery store is just a short walk away. I enjoyed eating breakfast on the small balcony and watching the people going by in the street below.
The location is excellent, very safe. The narrow streets provide shade from the hot sun. Be aware, however, that there is a huge street festival that goes on for two weeks (?) in August. The streets were absolutely packed with people in the evening and night. The windows have excellent soundproofing, but absurdly loud music was playing until 4AM one night, accompanied by drunk people yelling. This is not an on-going problem, but if you will be there in August, check the festival dates if you want to avoid the party. Normal street noise is kept well out.
Speaking of August ... the air conditioner is excellent! The place is well insulated, so it was not difficult to keep the temperature moderate during a blistering heatwave with daily highs of 106F/41C.
