Hector's place is very small. I do not recommend it if you cook on the stove often, the kitchen is particularly cramped. He also regularly brings friends into his apartment to chat and/or have dinner, so do not come if you expect things to be quiet and/or would prefer to not interact with/meet other people regularly while on your trip. If space is not a concern for you, and you are a very social person, I am sure you will have a fine time. Additionally, there are many flights of stairs and no elevator, so I would consider another place if you have a lot of luggage. His English is also not that great, so if you choose his place, be sure that your communication skills in Spanish are up to snuff.
I did not have a great time, but you probably will, if you think that Hector and his apartment will suit your needs and be a good fit for you.
