Plenty of great restaurants nearby. I made the mistake of walking south the first day in search of a SIM card and ATM (Google Maps directed me there being closer: Citibank was closed and you can't charge a SIM with credit card) and had a very tough time finding either or anyone who spoke English. Going north towards the city is the way to go. People tend to speak more English there and all the sites are in walking distance. I only took taxis home and to the airport.
Overall though finding people who spoke English presented a problem for me, more so than Brazil and Chile did.
The apartment itself is perfectly fine, however as best as I can tell it's bring your own Soap, Shampoo and extra Toilet Paper. I donated some so feel free to use it :) The shower is plenty hot which is a big plus for me as I like a hot shower. Also the washer/dryer are coin operated and coins are rare. Jony leaves some change on the counter which I think is for the laundry (I didn't actually do laundry myself so I can only speculate).
The elevator was an experience for me; it is the type you see in movies in a NYC loft.
The are was relatively quiet at night on weekdays but got a little loud on Friday and Saturday night. However the neighbors were a bit loud throughout the week. You an hear a lot of noises in the night, neighbors talking, using the bathroom, the fridge.
Also as you may be able to tell from the pictures, there are limited gard-rails on the loft. I don't imagine people with small children will be staying, but just in case it would be a bit dangerous for anyone less than maybe 10 y/o.
I didn't get to meet Jony so not speaking Spanish was a complication to getting in the building, but I managed to make my point to the custodian. Jony was very quick with email responses during the drip with suggestions and advise as requested.
