The good: Location cannot be any better. EVERYTHING is two steps away. It is really nice to have a TV in the bedroom. The apartment has a lot of little touches that are just very nice, like a small umbrella in case it rains, or a shopping cart to take to the market (which is less than a block away by the way), and the fact that they come to meet you when you check in and show you everything.
The not so good/tips: This is all on me, and it only applies to me and it really has nothing to do with the apartment, or the company that manages it. 1. If you are not familiar with the "capsule" type of coffee maker, make sure you get "Nespresso" capsules at the store; I learned that two boxes of the wrong capsules later. 2. If you are not familiar with a/c that has a dehumidifying function watch the youtube video on it, simple search just use the name of model and watch. Barcelona was very humid while I was there and I did not know about the function, so I kept trying to make the apartment comfortable between heat and cold function. 3. If you are not familiar with the European settings for the washer, watch the youtube video as well. There are different cycles and a few other things/symbols that are different. 4. I could have used a shelf or something like that in the bathroom, there is plenty of drawer space, I just like a shelf or something when there is not so much counter space.
