We stayed in Oscar's unit for 5 weeks. The location is perfect, as you're right beside some very nice grocery stores and shopping. There's also a WeWork a few minutes away if you need a space to work from.
The gym is well equipped for a condo building. The pool is a decent size as well. There is a jacuzzi tub, but don't expect it to be as hot as a typical Jacuzzi in Canada/USA. It's more of a "warm tub".
The only issues we had were related to the building itself and not the unit that we were renting. There were a number of times that the power went off unexpectedly, and there were some issues with the water in the unit below us, so they had to come into our unit several times to work on this.
There is a space heater available in case you're here in the colder months. The buildings aren't heated, so this is the only option for heat.
Oscar is an amazing host. He's very responsive, polite, and helpful. We've stayed in many Airbnbs, and he's definitely one of the best hosts we've had.
