Good points:
The physical location of the apartment is in the centre of everything. Great Shops and Restaurants, literally just out of your front door. Only 5 minutes walk to Placa d'Espanya to take the train or the bus, if visiting somewhere else on the Island.
The host provided by email, the day before, the keycode to gain entry to the front door, and the lock box where they apartment keys were to be found, and all this worked smoothly.
The dishwasher and washing machine worked well, and the host had left enough dishwasher tablets, and washing powder for the 7 day stay. Also enough rubbish sacks as the rubbish/recycling must be taken out every day (it is a warm country after all, so for hygiene reasons this is necessary), and deposited in the municipal bins for this purpose that can be found very locally. The host left clear instructions on this, with the locations, so I do not need to repeat it here, and it was very easy to accomplish each day on our way out.
Not so good points:
The central location (which will absolutely be of huge benefit for many) above the aforementioned shops and restaurants makes this apartment very, very noisy. Even though we both had ear plugs, we had interrupted sleep, because of this, every night.
In addition there was a lot of noise from the folks in the apartment above us. I do not think they were being inconsiderate, I just think by virtue of the hard floors, and lack of soft furnishings it ricochets the sound around and makes it louder and travel further.
The apartment, its fixtures and fittings were care worn and in some places rather grubby, nothing frightening, just not what I thought it should be. The listing states that the apartment is totally renovated, but that must have been some considerable time ago.
