We were staying in apartment 406. We were hearing squeaky noises from above. The building is really old and in the apartment upstairs you could hear them walk all the time. Our apartment was in the 4th floor which it seems to be more like 8 floors rather than 4. Think of this, you go to lisbon and you walk all day on the steep hills and you want to go back to the apartment and relax, but first you have to walk 8 floors. Another big issue I had was the toilet and the shower. The toilet was so small I literally couldn't sit properly to do my need. I'm 1.70cm 62kg and I couldn't fit. I can't imagine someone bigger than me going in to that toilet. I must admit this was funny, I even sent a Pic of the toilet to my friends. This toilet and the shower is a claustrophobic's worst nightmare trust me. The apartment was clean though and in a nice location in the center of lisbon. Overall I didn't really enjoy my stay in this apartment, all the noises, the stairs and the toilet&shower was outweighing the good things.
