This property is a supreme location, just off Plaza de Sol and surrounded by numerous nice restaurants and bars. The owners have done a nice job of putting in a modern home in a very old building. It is small, but they have done a good job of maximizing the space using a sliding door between bedroom and living space to allow a bigger feel and the balcony adds useful space. Having said that there are issues with incredibly noisy plumbing, complicated heat/AC and lack of places to hang towels. First the plumbing. Any time you or the neighbors run water., flush toilets or run the dishwasher there is a loud rushing sound,; maybe they had to install a forceful pumping system to get all the water up to this floor? Furthermore, you can not run any water, even kitchen sink while someone is showering or you completely lose water, We actually lost shower water twice for about 20 sec during our week stay when we were not using any other water source so we presume it was the neighbors usage that impacted this. The heating/cooling system is very complex. There are 2 thermostats, presumable one controls the forced air/AC system and the other controls the water heat. The former seemed easy enough to work out but on the 3rd day we came home and the place was way too hot. So we tried shutting off everything. The water heater thermostat then apparently kicked on and that was extremely noisy presumably due to the water issues described above. Some directions on how to use this would maybe help but am guessing that the temps of surrounding units probably impacts this the most. Those things are too difficult to fix so you just have to decide if you can tolerate it or not. But 2 things the owners could fix are:
1) provides some hooks to hang the towels. The only place to hang a towel is on the towel heater in the shower (which was covered in dust ). We actually had no hand towels while we were there which solved the problem of where to put any hand towels in the tiny bathroom.
2) ask the cleaning people not to put the wet mop back into the cupboard since it has no way to dry in there and then gets moldy. Any one with mold allergies would have a problem.
