Unfortunately, our experience was not good !
The localisation of the appartment is good (<15 min from Coliseo).
Neverthless, we found the appartment dirty.
Marta was very reactive and tried to help us (apparently they had a problem with the cleaning company). The person in charge was supposed to clean the house again but NOTHING changed ! And we had to send pictures of the dirt to Marta who came in person to solve the problem.
Finally, after the "3rd" cleaning, the room was clean. Unfortunately, the bathroom was still dirty (with a lot of hairs blocked in the shower).
