We enjoyed the accommodation and the location was fantastic. We highly recommend Trastevere. We had to call Marco a few times due to lack of instructions for check-in check out etc. He didn’t respond to our messages.
The accommodation was comfortable and generally had everything we needed although it is in need of some running repairs. The light at the apartment entrance wasn't working (very dark at night). The shower head sprays water everywhere.
The main down side was unfortunately the door to the apartment is very old and was hard to open. In fact, on one of the days the key actually broke off and left half the key in the key hole. Marco organised a locksmith who arrived 3 hours later but Marco made us pay the full amount of 160 euro to extract the key.
Our preference was for Marco to pay or at the very least share the cost given the very old state of the door and locks. When we explained to the locksmith that we found it hard to open he said "these doors are ancient". [Note: the lock now opens much easier as the locksmith lubricated it]. So, expect to pay if anything faulty breaks.
