We stayed at Rolando's place for 3 nights from June 24-27. We never met him directly but instead were assisted by his Roberto.
Roberto was very very helpful! He met us at the door when the taxi pulled up, he accommodated our delayed check-in due to a train delay, and he helped us get the luggage upstairs. The elevator is very small and tight but he was very helpful in helping us manage that.
(He was very sweet - He even walked us over to the nearest sports bar so we could watch our football match)
The location is unbeatable - we are very near to a lot of major attractions and were able to walk everywhere. It is a busy but a very safe location.
The apartment was super clean - something that was very important to us. The room is spacious and the bed was comfortable. The AC works very well and our sleeps were very comfortable.
The only downside was the size of the bathroom - it was also very clean, but it is quite narrow. It would be difficult for a tall or a big person to be comfortable using the toilet or navigate the shower. However, it could be that we're used to larger spaces in Canada (maybe we're spoiled:P). If you're used to European sizes for rooms like in England, then perhaps this will not be an issue for you.
Both Rolando and Roberto were also quick to respond to any questions or concerns and made our stay there very comfortable. We would recommend this place.
