It is a basement apartment, but there are windows and light does come in. It is really impeccably clean, organized in a perfect way for a traveler and has just enough amenities so that you are comfortable and have a spacious place to call home for a stay. I was here a week, in town working and Marina's sister greeted me, gave me a key and showed me around. She was very kind and helpful when I had questions. The only suggestion I might make ( and this is for all airbnb hosts, not just this one) is that whenever there are any systems, such as remote controls, a/c, etc, it would be helpful to have written instructions or photos to show how to use them. I hate having to bother hosts to ask them for these things and I know as a host, it's easier to not have to repeat the info all the time. I had a great stay and hope to stay again in the future when I'm in town working again.
