What's not to like? The building is, I think, a year old and so too, of course, is the apartment. It presents very well and everything in it was new looking.
The hot water was always there and never ran out.
The WiFi was reliable.
Traffic noise was a minor problem. That's the price you pay for facing a street as opposed the back. With the balcony doors closed the noise is low, and infrequent after 11 PM or so, and shouldn't prevent anyone but the lightest of sleepers from having a great rest on the firm bed. I have earplugs but didn't need to use them - and I'm a pretty light sleeper myself.
The balcony is nice to lounge on later in the day. It gets the morning sun so, well, that's too hot for me.
Carlos, Martin's father, checked me in and out. He's very nice and was accommodating of the 8 AM checkout I needed. (He said anytime from 7 until 11 AM was fine.)
All in all it was a great one week stay.
