Staying with Mercedes was a great experience. She was super warm and offered great recommendations around the area.
Her place is extremely well located and you can easily discount the 5 flights of stairs to the apartment! We had open access to her kitchen (where she also kept refrigerated bottled water). Despite there being no air-conditioning, the room was quite cool with the window open. The bed was comfortable and my friend and I slept very well! The room is a bit small, but everything else makes up for it.
Her dog, Stevie is absolutely the sweetest. You will fall in love with him the minute you meet him.
Mercedes was very kind to offer us wine both the evenings we were there along with some munchies! She was very good company and we had a really good conversation with her. We look forward to staying/meeting her again!
