Alex and his place are great! His home is centrally located near all the main attractions and there are tons of restaurants a stones throw away. The room is cozy and has a good sized bed. Alex himself is a phenomenal host. He is thorough, accommodating, and leaves you feeling informed on the city. I would definitely stay with him again.
The only thing I would warn against is bringing a larger than average suitcase as the stair case up to the room is narrow.
