Miguel's apartment was great! It is all you really need while on vacation, excellent location, very comfy, and exceptionally clean.
The apartment is located in the middle of Alfama where many locals and tourist cross paths everyday.
Even thought there is no security guard we felt very secure. The door had a great lock, and there was a market (convenience store) very close to the apartment open almost all night.
Overall we had a great experience and we definitely recommend Miguel's apartment.
