This apartment has one bathroom and a very "funky" shower as others have also commented. We were a family of 5 staying here I wouldn't return. 1 bathroom is not good for 5 people and the bathroom is also not very functional. For instance the sink has no shelf space to put anything and there are not enough hooks to hold all the towels for five people. On the third day we were there they decided to have a plumber come in and do some work on the bathroom. They said it would only take 30 minutes but ended up Taki g several hours and when we came back from our morning activities from the sweltering heat, they were still there working on the bathroom. We wanted to take a rest for a while before heading back out. I lost use of the apartment for a period of time as I had to leave due to the stench and awkwardness of the situation. When we returned there was dust all over from the grouting the plumber had done. My wife had to actually clean up a little.
Also, the location is not great. It is close to the colloseum but it is on the side that is further away from most of the popular sites so it is a long walk to most things.
I wouldn't recommend this place for any more than 3 people most and even if my party was smaller I wouldn't stay here again due to the lack of consideration and inconvenience given to us.
