While the apartment is located in the beautiful Barcelona in a very nice neighborhood with safe environment there were some issues related to the apartment which I would like to share.
There were no towels in the apartment (I may missed this disclosure in the descriptions; but who travels with their own towels across the ocean anyways?). It should be default.
The host however provided my with the towers after I requested them.
Also, there was just a minimum hot water in the shower. My family of four people could not take a normal hot shower for the whole trip! When I was trying to communicate this issue, the host replied that it should work OK and never show up to fix it. Well, I tell you: it is not OK. It lasts for 3-4 minutes if you use just low amount of water and even less if you increase the water stream.
Another thing which could be better is the heater. I.e. there was no heating at all in the apartment. End of December in Barcelona could be really chilly! The host could provide a portable cheap unit for a $30-50!
