We had a wonderful stay at Charles´place! The communication was fluent, someone was waiting for us at the apartment , gave us recommendations for food (highly recommend to go to Cerveceria Trinidade, amazing sea food) and we got a welcome bottle of wine.
The views of the apartment are amazing, the bathroom is clean and new and we had fresh towels. The location of the apartment is right in the center which is very convenient but I do have to say that is located in a corner where at night there are people selling drugs but this happens pretty much in the whole center of Lisbon after 8pm, so just keep walking and you will be fine.
I can only recommend this place, it was amazingl ! A very important highlight is that normally apartments in the center are very noisy but this was not the case, we slept really well!
