Getting to this room requires climbing 2 steep staircases. Piero's apartment covers the entire top floor of this building. This room is partitioned off from the rest of the apartment and has a separate entrance. The partition does let through a little bit of light from the main apartment, but it's not too noticeable. In order to get between this room and the rest of the apartment (to access the bathroom and kitchen), you have to exit the room and go down the hallway to the main apartment entrance. The bedroom and the main apartment use the same key, since they are technically both entrances to the same apartment. The curtains in the bedroom let in very little outside light, and the air conditioner works excellently. I am not a deep sleeper but I never had any trouble sleeping in the room.
I arrived around midnight with my girlfriend, and Piero's friend let us in. His friend did not speak English, but attempted to explain things to me in Spanish. This was confusing, because I don't know Spanish very well, but it was not a problem because Piero was readily available over text or phone to answer any questions in English. I met another guy who was living in the main apartment before I met Piero - this confused me at first, because I wasn't sure if the guy I met was Piero. I did not meet Piero until a few days into my stay; he owns a number of properties and doesn't always stay at this apartment. Piero looks exactly like his profile photo; if you meet someone who looks different it's not him.
I stayed here for 1 month, and it was excellent. The bed is extremely comfortable, the kitchen is well stocked with cooking supplies, and the shower has great temperature and water pressure. Piero stocked the kitchen with bottled water as well and offered me some Dominican rum. I can't recommend this place enough!
