Ricardo and Anna are wonderful hosts! I am so glad to have met them! My only regret is that I don't speak Spanish so I didn't get to know them as thoroughly as I would have liked! This was my first trip to Havana, traveling alone, and I feel lucky that I landed where I did. I was able to get on an earlier flight to Havana so I was at their house earlier. I negotiated a $20 CUC cab ride from the airport to their house. Damariss (I hope I get the spelling correct), who works at the house, was there to meet me and fixed me some coffee and offered help with transportation. She gave me the key and showed me the room which is exactly as represented. Her welcoming smile and great sense of humor was nice to arrive to every morning! Everything was very clean and it was perfect for my 5 night stay. They have 3 rooms (I believe) at the house, perfectly situated for renting since each room has a separate entrance and key. Mine was up a set of outside stairs and off from a nice patio with seating (that I used). It had its own bathroom, clean and with fresh towels, if needed, every day and felt very private. I didn't even know anyone else was staying there until after my 2nd night. They provided a lovely breakfast that I took in their sweet courtyard with two tables for seating. The neighborhood is busy with people walking from work or to school. At night, they have security in the courtyard, but I never once felt unsafe in all of Havana. This was an extra comfort, however. You need to take a cab, or the better value, a collectivo, to get to Old Havana, the Melocan, and Vedado. I got taken to the cleaners on the cab rides at first paying $30 USD equivalent (CUC) one-way my first day...the collectivos are literally $.25 USD equivalent. You can get a cab for $10 CUC (same as $10 USD) one-way when the collectivos might not have other passengers. All of those locations are about 10-20 minutes away depending on the time of day. You can get those rides with a 5 minute walk to 3rd street or slightly less to 5th street.
I can't tell you how much I appreciate Ricardo and Anna and how friendly and accommodating they were. Anna loaned me sandals for when I went to the beach one day. When they found out it was my birthday, Anna, Damariss and another wonderful lady who works there presented me with a small cake and candle and sang Happy Birthday to me :) So nice.
Take good care! I would recommend their house to anyone.
